bf433e5f46 Tweak this test. We can analyze what happens and show that we still do the 
right thing, instead of merely being unable to analyze and the transform
doesn't occur.

c14bc77315 Add more analysis of the sign bit of an srem instruction. If the LHS is negative 
then the result could go either way. If it's provably positive then so is the
srem. Fixes PR9343 #7!

d01f50f42c ConstantInt has some getters which return ConstantInt's or ConstantVector's of 
the value splatted into every element. Extend this to getTrue and getFalse which
by providing new overloads that take Types that are either i1 or <N x i1>. Use
it in InstCombine to add vector support to some code, fixing PR8469!

7cefa640de Revert r127073: "Introduce $(ECHOPATH) to print DOSish path string on MSYS bash for alternative of $(ECHO)." 
It broke the llvm-gcc-native-mingw32 buildbot, and we need all of them to be green for the 2.9 branch.

Takumi, please reapply after we branch, preferably with a fix ;-)

58bfcdbcf6 Thread comparisons over udiv/sdiv/ashr/lshr exact and lshr nuw/nsw whenever 
possible. This goes into instcombine and instsimplify because instsimplify
doesn't need to check hasOneUse since it returns (almost exclusively) constants.

This fixes PR9343 #4 #5 and #8!

31cbac1cfe Allow vector shifts (shl,lshr,ashr) on SPU. 
There was a previous implementation with patterns that would 
have matched e.g. 
	shl <v4i32> <i32>,
but this is not valid LLVM IR so they never were selected.

3a73e343d0 Teach instruction simplify to use constant ranges to solve problems of the form 
"icmp pred %X, CI" and a number of examples where "%X = binop %Y, CI2".

Some of these cases (div and rem) used to make it through opt -O2, but the
others are probably now making code elsewhere redundant (probably instcombine).

- Allow selection of PTX Version and Shader Model as sub-target attributes.
- Merge integer/floating-point test cases for load/store.
