[mips] Correct and improve special-case shuffle instructions.
Summary:
The documentation writes vectors highest-index first whereas LLVM-IR writes
them lowest-index first. As a result, instructions defined in terms of
left_half() and right_half() had the halves reversed.
In addition to correcting them, they have been improved to allow shuffles
that use the same operand twice or in reverse order. For example, ilvev
used to accept masks of the form:
<0, n, 2, n+2, 4, n+4, ...>
but now accepts:
<0, 0, 2, 2, 4, 4, ...>
<n, n, n+2, n+2, n+4, n+4, ...>
<0, n, 2, n+2, 4, n+4, ...>
<n, 0, n+2, 2, n+4, 4, ...>
One further improvement is that splati.[bhwd] is now the preferred instruction
for splat-like operations. The other special shuffles are no longer used
for splats. This lead to the discovery that <0, 0, ...> would not cause
splati.[hwd] to be selected and this has also been fixed.
This fixes the enc-3des test from the test-suite on Mips64r6 with MSA.

[X86] ABI change for x86-32: pass 3 vector arguments in-register instead of 4, except on Darwin.
This changes the ABI used on 32-bit x86 for passing vector arguments.
Historically, clang passes the first 4 vector arguments in-register, and additional vector arguments on the stack, regardless of platform. That is different from the behavior of gcc, icc, and msvc, all of which pass only the first 3 arguments in-register.
The 3-register convention is documented, unofficially, in Agner's calling convention guide, and, officially, in the recently released version 1.0 of the i386 psABI.
Darwin is kept as is because the OS X ABI Function Call Guide explicitly documents the current (4-register) behavior.

ARM: allow jump tables to be placed as constant islands.
Previously, they were forced to immediately follow the actual branch
instruction. This was usually OK (the LEAs actually accessing them got emitted
nearby, and weren't usually separated much afterwards). Unfortunately, a
sufficiently nasty phi elimination dumps many instructions right before the
basic block terminator, and this can increase the range too much.
This patch frees them up to be placed as usual by the constant islands pass,
and consequently has to slightly modify the form of TBB/TBH tables to refer to
a PC-relative label at the final jump. The other jump table formats were
already position-independent.

At the present time, we don't have a way to represent general dependency

to model WRITE_REGISTER as writing (which we had been doing) and model

[DAGCombine] Be more pedantic about use iteration in CombineToPreIndexedLoadStore
In CombineToPreIndexedLoadStore, when the offset is a constant, we have code
that looks for other uses of the pointer which are constant offset computations
so that they can be rewritten in terms of the updated pointer so that we don't
need to keep a copy of the base pointer to compute these constant offsets.
Unfortunately, when it iterated over the uses, it did so by SDNodes, and so we
could confuse ourselves if the base pointer was produced by a node that had
multiple results (because we would not immediately exclude uses of the other
node results). This was reported as PR22755. Unfortunately, we don't have a
test case (and I've also been unable to produce one thus far), but at least the
mistake is clear. The right way to fix this problem is to make use of the information
contained in the use iterators to filter out any uses of other results of the
node producing the base pointer.
This should be mostly NFC, but should also fix PR22755 (for which,
unfortunately, we have no in-tree test case).

[PowerPC] Add extra r2 read deps on @toc@l relocations
If some commits are happy, and some commits are sad, this is a sad commit. It
is sad because it restricts instruction scheduling to work around a binutils
linker bug, and moreover, one that may never be fixed. On 2012-05-21, GCC was
updated not to produce code triggering this bug, and now we'll do the same...
When resolving an address using the ELF ABI TOC pointer, two relocations are
generally required: one for the high part and one for the low part. Only
the high part generally explicitly depends on r2 (the TOC pointer). And, so,
we might produce code like this:
.Ltmp526:
addis 3, 2, .LC12@toc@ha
.Ltmp1628:
std 2, 40(1)
ld 5, 0(27)
ld 2, 8(27)
ld 11, 16(27)
ld 3, .LC12@toc@l(3)
rldicl 4, 4, 0, 32
mtctr 5
bctrl
ld 2, 40(1)
And there is nothing wrong with this code, as such, but there is a linker bug
in binutils (https://sourceware.org/bugzilla/show_bug.cgi?id=18414) that will
misoptimize this code sequence to this:
nop
std r2,40(r1)
ld r5,0(r27)
ld r2,8(r27)
ld r11,16(r27)
ld r3,-32472(r2)
clrldi r4,r4,32
mtctr r5
bctrl
ld r2,40(r1)
because the linker does not know (and does not check) that the value in r2
changed in between the instruction using the .LC12@toc@ha (TOC-relative)
relocation and the instruction using the .LC12@toc@l(3) relocation.
Because it finds these instructions using the relocations (and not by
scanning the instructions), it has been asserted that there is no good way
to detect the change of r2 in between. As a result, this bug may never be
fixed (i.e. it may become part of the definition of the ABI). GCC was
updated to add extra dependencies on r2 to instructions using the @toc@l
relocations to avoid this problem, and we'll do the same here.
This is done as a separate pass because:
1. These extra r2 dependencies are not really properties of the
instructions, but rather due to a linker bug, and maybe one day we'll be
able to get rid of them when targeting linkers without this bug (and,
thus, keeping the logic centralized here will make that
straightforward).
2. There are ISel-level peephole optimizations that propagate the @toc@l
relocations to some user instructions, and so the exta dependencies do
not apply only to a fixed set of instructions (without undesirable
definition replication).
The test case was reduced with the help of bugpoint, with minimal cleaning. I'm
looking forward to our upcoming MI serialization support, and with that, much
better tests can be created.

Canonicalize min/max expressions correctly.
This patch introduces a canonical form for min/max idioms where one operand
is extended or truncated. This often happens when the other operand is a
constant. For example:
%1 = icmp slt i32 %a, i32 0
%2 = sext i32 %a to i64
%3 = select i1 %1, i64 %2, i64 0

[MemCpyOpt] Turn memcpy from just-memset'd source into memset.
There's no point in copying around constants, so, when all else fails,
we can still transform memcpy of memset into two independent memsets.
To quote the example, we can turn:
memset(dst1, c, dst1_size);
memcpy(dst2, dst1, dst2_size);
into:
memset(dst1, c, dst1_size);
memset(dst2, c, dst2_size);
When dst2_size <= dst1_size.
Like r235232 for copy constructors, this can occur in move constructors.

[PPC64] Add vector pack/unpack support from ISA 2.07
This patch adds support for the following new instructions in the
Power ISA 2.07:
vpksdss
vpksdus
vpkudus
vpkudum
vupkhsw
vupklsw
These instructions are available through the vec_packs, vec_packsu,
vec_unpackh, and vec_unpackl built-in interfaces. These are
lane-sensitive instructions, so the built-ins have different
implementations for big- and little-endian, and the instructions must
be marked as killing the vector swap optimization for now.
The first three instructions perform saturating pack operations. The
fourth performs a modulo pack operation, which means it can be
represented with a vector shuffle, and conversely the appropriate
vector shuffles may cause this instruction to be generated. The other
instructions are only generated via built-in support for now.
Appropriate tests have been added.
There is a companion patch to clang for the rest of this support.

MC: Merge MCSymbol and MCSymbolData
Turn `MCSymbolData` into a field inside of `MCSymbol`. Keep all the old
API alive for now, so that consumers can be updated in a later commit.
This means we still temporarily need the back pointer from
`MCSymbolData` to `MCSymbol`, but I'll remove it in a follow-up.
This optimizes for object emission over assembly emission. By removing
the `DenseMap` in `MCAssembler`, llc memory usage drops from around 1040
MB to 1001 MB (3.8%).
(I'm looking at `llc` memory usage on `verify-uselistorder.lto.opt.bc`;

Instead of an intrusive double-linked linked list, use a

`MCSymbolData`. Otherwise, no functionality change here.
While I measured a memory drop from around 1047MB to 1040MB (0.6%) --
and this is a decent cleanup in its own right -- it's primarily a
