SimplifyCFG: If convert single conditional stores
This resurrects r179957, but adds code that makes sure we don't touch
atomic/volatile stores:
This transformation will transform a conditional store with a preceeding
uncondtional store to the same location:
a[i] =
may-alias with a[i] load
if (cond)
a[i] = Y
into an unconditional store.
a[i] = X
may-alias with a[i] load
tmp = cond ? Y : X;
a[i] = tmp
We assume that on average the cost of a mispredicted branch is going to be
higher than the cost of a second store to the same location, and that the
secondary benefits of creating a bigger basic block for other optimizations to
work on outway the potential case where the branch would be correctly predicted
and the cost of the executing the second store would be noticably reflected in
performance.
hmmer's execution time improves by 30% on an imac12,2 on ref data sets. With
this change we are on par with gcc's performance (gcc also performs this
transformation). There was a 1.2 % performance improvement on a ARM swift chip.
Other tests in the test-suite+external seem to be mostly uninfluenced in my
experiments:
This optimization was triggered on 41 tests such that the executable was
different before/after the patch. Only 1 out of the 40 tests (dealII) was
reproducable below 100% (by about .4%). Given that hmmer benefits so much I
believe this to be a fair trade off.

Handle tied sub-operands in AsmMatcherEmitter
The problem this patch addresses is the handling of register tie
constraints in AsmMatcherEmitter, where one operand is tied to a
sub-operand of another operand. The typical scenario for this to
happen is the tie between the "write-back" register of a pre-inc
instruction, and the base register sub-operand of the memory address
operand of that instruction.
The current AsmMatcherEmitter code attempts to handle tied
operands by emitting the operand as usual first, and emitting
a CVT_Tied node when handling the second (tied) operand. However,
this really only works correctly if the tied operand does not
have sub-operands (and isn't a sub-operand itself). Under those
circumstances, a wrong MC operand list is generated.
In discussions with Jim Grosbach, it turned out that the MC operand
list really ought not to contain tied operands in the first place;
instead, it ought to consist of exactly those operands that are
named in the AsmString. However, getting there requires significant
rework of (some) targets.
This patch fixes the immediate problem, and at the same time makes
one (small) step in the direction of the long-term solution, by
implementing two changes:
1. Restricts the AsmMatcherEmitter handling of tied operands to
apply solely to simple operands (not complex operands or
sub-operand of such).
This means that at least we don't get silently corrupt MC operand
lists as output. However, if we do have tied sub-operands, they
would now no longer be handled at all, except for:
2. If we have an operand that does not occur in the AsmString,
and also isn't handled as tied operand, simply emit a dummy
MC operand (constant 0).
This works as long as target code never attempts to access
MC operands that do no not occur in the AsmString (and are
not tied simple operands), which happens to be the case for
all targets where this situation can occur (ARM and PowerPC).
[ Note that this change means that many of the ARM custom
converters are now superfluous, since the implement the
same "hack" now performed already by common code. ]
Longer term, we ought to fix targets to never access *any*
MC operand that does not occur in the AsmString (including
tied simple operands), and then finally completely remove
all such operands from the MC operand list.
Patch approved by Jim Grosbach.

the way they preserve the other flags. Like MachineMemOperands in

code.

ARM: Fix encoding of hint instruction for Thumb.
"hint" space for Thumb actually overlaps the encoding space of the CPS
instruction. In actuality, hints can be defined as CPS instructions where imod
and M bits are all nil.
Handle decoding of permitted nop-compatible hints (i.e. nop, yield, wfi, wfe,
sev) in DecodeT2CPSInstruction.

PowerPC: Use RegisterOperand instead of RegisterClass operands
In the default PowerPC assembler syntax, registers are specified simply
by number, so they cannot be distinguished from immediate values (without
looking at the opcode). This means that the default operand matching logic
for the asm parser does not work, and we need to specify custom matchers.
Since those can only be specified with RegisterOperand classes and not
directly on the RegisterClass, all instructions patterns used by the asm
parser need to use a RegisterOperand (instead of a RegisterClass) for
all their register operands.
This patch adds one RegisterOperand for each RegisterClass, using the
same name as the class, just in lower case, and updates all instruction
patterns to use RegisterOperand instead of RegisterClass operands.

Mips assembler: .set reorder support
Mips have delayslots for certain instructions
like jumps and branches. These are instructions
that follow the branch or jump and are executed
before the jump or branch is completed.
Early Mips compilers could not cope with delayslots
and left them up to the assembler. The assembler would
fill the delayslots with the appropriate instruction,
usually just a nop to allow correct runtime behavior.
The default behavior for this is set with .set reorder.
To tell the assembler that you don't want it to mess with
the delayslot one used .set noreorder.
For backwards compatibility we need to support
.set reorder and have it be the default behavior in the
assembler.
Our support for it is to insert a NOP directly after an
instruction with a delayslot when in .set reorder mode.

Fix for r180193 - MI Sched: eliminate local vreg.
Fixes PR15838. Need to check for blocks with nothing but dbg.value.
I'm not sure how to force this situation with a unit test. I tried to
reduce the test case in PR15838 (1k lines of metadata) but gave up.

[objc-arc] Added ImpreciseAutoreleaseSet to track autorelease calls that were once autoreleaseRV instructions.
Due to the semantics of ARC, we must be extremely conservative with autorelease
calls inserted by the frontend since ARC gaurantees that said object will be in
the autorelease pool after that point, an optimization invariant that the
optimizer must respect.
On the other hand, we are allowed significantly more flexibility with
autoreleaseRV instructions.
Often times though this flexibility is disrupted by early transformations which
transform objc_autoreleaseRV => objc_autorelease if said instruction is no
longer being used as part of an RV pair (generally due to inlining). Since we
can not tell the difference in between an autorelease put into place by the
frontend and one created through said ``strength reduction'' we can not perform
these optimizations.
The addition of this set gets around said issues by allowing us to differentiate
in between said two cases.

Use pointers to iterate over symbols.
While here, don't report a dummy symbol for relocations that don't have symbols.
We used to says such relocations were for the first defined symbol, but now we
return end_symbols(). The llvm-readobj output change agrees with otool.

Don't produce an empty llvm.compiler.used in LTO.
LTO was always creating an empty llvm.compiler.used. With this patch we
now first check if there is anything to be added first.
Unfortunately, there is no good way to test libLTO in isolation as it needs gold
or ld64, but there are bots doing LTO builds that found this problem.

That seems to interact poorly with the environ and _environ macros

Also remove the incorrect comment about _NSGetEnviron().
