[x86] Teach the new vector shuffle lowering code to handle what is
essentially a DAG combine that never gets a chance to run.
We might typically expect DAG combining to remove shuffles-of-splats and
other similar patterns, but we don't get a chance to run the DAG
combiner when we recursively form sub-shuffles during the lowering of
a shuffle. So instead hand-roll a really important combine directly into
the lowering code to detect shuffles-of-splats, especially shuffles of
an all-zero splat which needn't even have the same element width, etc.
This lets the new vector shuffle lowering handle shuffles which
implement things like zero-extension really nicely. This will become
even more important when I wire the legalization of zero-extension to
vector shuffles with the new widening legalization strategy.

ARM: properly lower dllimport'ed global values
This completes the handling for DLL import storage symbols when lowering

This is particularly important for non-function symbols as it is possible to
handle function references by emitting a thunk which performs the translation
from the unprefixed __imp_ symbol to the proper symbol (although, this is a
non-optimal lowering). For a variable symbol, no such thunk can be

with as few dependencies on other instructions as possible. The aim is to
be very confident that each LLVM-IR instruction is implemented correctly and
with the optimal sequence of instructions, as well as to make it easy to tell
what is tested, and make it easier to bring up new ISA revisions in the
future. This gives us a good foundation on which to test bigger things.
These particular tests will allow testing that MIPS32r6/MIPS64r6 generate
the correct return instruction for returns, calls, and indirect branches.
This will be a bit tricky since the assembly text is identical but the
instruction is actually different. On MIPS32r6/MIPS64r6 'jr $rs' has been
removed in favour of the equivalent 'jalr $zero, $rs'. 'jr $rs' remains as
an alias for 'jalr $zero, $rs'.

[CostModel][x86] Improved cost model for alternate shuffles.
This patch:
1) Improves the cost model for x86 alternate shuffles (originally
added at revision 211339);
2) Teaches the Cost Model Analysis pass how to analyze alternate shuffles.
Alternate shuffles are a special kind of blend; on x86, we can often
easily lowered alternate shuffled into single blend
instruction (depending on the subtarget features).
The existing cost model didn't take into account subtarget features.
Also, it had a couple of "dead" entries for vector types that are never
legal (example: on x86 types v2i32 and v2f32 are not legal; those are
always either promoted or widened to 128-bit vector types).
The new x86 cost model takes into account what target features we have
before returning the shuffle cost (i.e. the number of instructions
after the blend is lowered/expanded).
This patch also teaches the Cost Model Analysis how to identify and analyze
alternate shuffles (i.e. 'SK_Alternate' shufflevector instructions):
- added function 'isAlternateVectorMask';
- added some logic to check if an instruction is a alternate shuffle and, in
case, call the target specific TTI to get the corresponding shuffle cost;
- added a test to verify the cost model analysis on alternate shuffles.
