ca4475dd7b Add patterns to match conditional moves with loads folded 
into their left operand, rather than their right. Do this
by commuting the operands and inverting the condition.

98fdf706f7 Improve support for type-generic vector intrinsics by teaching TableGen how 
to handle LLVMMatchType intrinsic parameters, and by adding new subclasses
of LLVMMatchType to match vector types with integral elements that are 
either twice as wide or half as wide as the elements of the matched type.

4edc9d725b Now that fold-pcmpeqd-0.ll is effectively testing that scheduling helps 
avoid the need for spilling, add a new testcase that tests that the
pcmpeqd used for V_SETALLONES is changed to a constant-pool load as
needed.

e033f7c41e Revert r42653 and forward-port the code that lets INC64_32r be 
converted to LEA64_32r in x86's convertToThreeAddress. This
replaces code like this:
   movl  %esi, %edi
   inc   %edi
with this:
   lea   1(%rsi), %edi
which appears to be beneficial.

- Add preliminary support for v2i32; load/store generates the right code but
  there's a lot work to be done to make this vector type operational.

b19f5073f9 Fix a bug in ComputeLinearIndex computation handling multi-level 
aggregate types. Don't increment the current index after reaching
the end of a struct, as it will already be pointing at
one-past-the end. This fixes PR3288.

1f1e4ab65a The phi construction algorithm used for interval reconstruction is complicated by 
two address instructions.  We need to keep track of things we've processed AS USES
independetly of whether we've processed them as defs.

This fixes all known miscompilations when reconstruction is turned on.

c30557841b CellSPU: 
- Fix bugs 3194, 3195: i128 load/stores produce correct code (although, we
  need to ensure that i128 is 16-byte aligned in real life), and 128 zero-
  extends are supported.
- New td file: SPU128InstrInfo.td: this is where all new i128 support should
  be put in the future.
- Continue to hammer on i64 operations and test cases; ensure that the only
  remaining problem will be i64 mul.

1cdb677fc8 Use a latency value of 0 for the artificial edges inserted by 
AddPseudoTwoAddrDeps. This lets the scheduling infrastructure
avoid recalculating node heights. In very large testcases this
was a major bottleneck. Thanks to Roman Levenstein for finding
this!

As a side effect, fold-pcmpeqd-0.ll is now scheduled better
and it no longer requires spilling on x86-32.

3b98802e9a Delete unused global aliases with internal linkage. 
In fact this also deletes those with linkonce linkage,
however this is currently dead because for the moment
aliases aren't allowed to have this linkage type.
