This patch implements the PPCDAGToDAGISel::PostprocessISelDAG virtual
method to perform post-selection peephole optimizations on the DAG
representation.
One optimization is implemented here: folds to clean up complex
addressing expressions for thread-local storage and medium code
model. It will also be useful for large code model sequences when
those are added later. I originally thought about doing this on the
MI representation prior to register assignment, but it's difficult to
do effective global dead code elimination at that point. DCE is
trivial on the DAG representation.
A typical example of a candidate code sequence in assembly:
addis 3, 2, globalvar@toc@ha
addi 3, 3, globalvar@toc@l
lwz 5, 0(3)
When the final instruction is a load or store with an immediate offset
of zero, the offset from the add-immediate can replace the zero,
provided the relocation information is carried along:
addis 3, 2, globalvar@toc@ha
lwz 5, globalvar@toc@l(3)
Since the addi can in general have multiple uses, we need to only
delete the instruction when the last use is removed.

Mips specific standalone assembler directive "set at".
This directive changes the general purpose register

GPR register names for temporaries between old abi

During lowering of a BUILD_VECTOR, we look for opportunities to use a
vector splat. When the splatted value fits in 5 signed bits, a single
splat does the job. When it doesn't fit in 5 bits but does fit in 6,
and is an even value, we can splat on half the value and add the result
to itself.
This last optimization hasn't been working recently because of improved
constant folding. To circumvent this, create a pseudo VADD_SPLAT that
can be expanded during instruction selection.

In some cases, we were losing track of live implicit registers which
was creating dead defs and causing the scheduler to produce invalid
code.

fields were only ever set in the constructor. The create method retains
its consistent interface so that these bits can be re-threaded through
the emitter if they're ever needed.
This was found by the -Wunused-private-field Clang warning.

If the memcpy has an odd length with an alignment of 2, this would incorrectly
assert on the last 1 byte copy.

at this time, llvm is generating a different but equivalent pattern
that would lead to this instruction. I am trying to think of a way
to get it to generate this. If I can't, I may just remove the pseudo.

This expansion will be moved to expandISelPseudos as soon as I can figure
out how to do that. There are other instructions which use this
ExpandFEXT_T8I816_ins and as soon as I have finished expanding them all,
I will delete the macro asm string text so it has no way to be used
in the future.

GCC warns about the attribute being ignored if it occurs after void*.
There seems to be some kind of incompatibility between clang and gcc here, but
I can't fathom who's right.
void* LLVM_LIBRARY_VISIBILITY foo(); // clang: hidden, gcc: default
LLVM_LIBRARY_VISIBILITY void *bar(); // clang: hidden, gcc: hidden
void LLVM_LIBRARY_VISIBILITY qux(); // clang: hidden, gcc: hidden

It's completely unnecessary and can be replace with proper
SReg_64 handling instead.
This actually fixes a piglit test on SI.

set special classes as not allocatable
v3: revert setting special classes as not allocateable

Seems to be allot simpler, and also paves the
way for further improvements.
v2: rebased on master, use 0 in BUFFER_LOAD_FORMAT_XYZW,
use VGPR0 in dummy EXP, avoid compiler warning, break
after encoding the first literal.
v3: correctly use V_ADD_F32_e64
