[mips] Add tests for the 'ret', 'call', and 'indirectbr' LLVM IR instruction.
Summary:
The tests in this directory are intended to test a single IR instruction
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'.

With this fix, the code generated with the widening legalization

[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.

Fix ppcf128 component access on little-endian systems
The PowerPC 128-bit long double data type (ppcf128 in LLVM) is in fact a
pair of two doubles, where one is considered the "high" or
more-significant part, and the other is considered the "low" or
less-significant part. When a ppcf128 value is stored in memory or a
register pair, the high part always comes first, i.e. at the lower
memory address or in the lower-numbered register, and the low part
always comes second. This is true both on big-endian and little-endian
PowerPC systems. (Similar to how with a complex number, the real part
always comes first and the imaginary part second, no matter the byte
order of the system.)
This was implemented incorrectly for little-endian systems in LLVM.
This commit fixes three related issues:
- When printing an immediate ppcf128 constant to assembler output
in emitGlobalConstantFP, emit the high part first on both big-
and little-endian systems.
- When lowering a ppcf128 type to a pair of f64 types in SelectionDAG
(which is used e.g. when generating code to load an argument into a
register pair), use correct low/high part ordering on little-endian
systems.
- In a related issue, because lowering ppcf128 into a pair of f64 must
operate differently from lowering an int128 into a pair of i64,
bitcasts between ppcf128 and int128 must not be optimized away by the
DAG combiner on little-endian systems, but must effect a word-swap.

This still would promote vNi1 vectors to get the masks right, but would

strategy outside of vNi1 cases, but it is very hard to test the
rammifications of that and fix bugs in widening-based legalization
