Bruno Cardoso Lopes 91d61df3eb Add AVX matching patterns to Packed Bit Test intrinsics. 
Apply the same approach of SSE4.1 ptest intrinsics but
create a new x86 node "testp" since AVX introduces
vtest{ps}{pd} instructions which set ZF and CF depending
on sign bit AND and ANDN of packed floating-point sources.

This is slightly different from what the "ptest" does.
Tests comming with the other 256 intrinsics tests.

Owen Anderson 5f1dd0967d Now that we're using ConstantRange to represent potential values, make use of that represenation to 
create constraints from comparisons other than eq/neq.

Ted Kremenek 19183acd1f Add test case for <rdar://problem/8288645>. While this is fixed in trunk, we previously were getting the following assertion failure not too long ago: 
Assertion failed: (getContainingDC(DC) == CurContext && "The next DeclContext should be lexically contained in the current one.")

John Thompson 307c2729fd Something's wrong with this test on other platforms. I'll probably need to simplify it later. For now revert.

Nate Begeman 265363061e Add the minimal amount of smarts necessary to instcombine of shufflevectors to recognize 
patterns generated by clang for transpose of a matrix in generic vectors.  This is made
of two parts:

1) Propagating vector extracts of hi/lo half into their users
2) Recognizing an insertion of even elements followed by the odd elements as an unpack.

Testcase to come, but this shrinks the # of shuffle instructions generated on x86 from ~40 to the minimal 8.

a register before checking if it was defined.

Johnny Chen 705c3b6aaa There is no need to restore (sys.stdin, sys.stdout) of the python script 
interpreter right before calling Py_Finalize().  This also fixed the crash as
reported in rdar://problem/8252903.

Jakob Stoklund Olesen 57f3db6e2e Give up on register class recalculation when the register is used with subreg 
operands. We don't currently have a hook to provide "the largest super class of
A where all registers' getSubReg(subidx) is valid and in B".

Jakob Stoklund Olesen 3b870f045f Avoid editing the current live interval during remat. 
The live interval may be used for a spill slot as well, and that spill slot
could be shared by split registers. We cannot shrink it, even if we know the
current register won't need the spill slot in that range.

Evan Cheng 3f251fb26e Re-apply r110655 with fixes. Epilogue must restore sp from fp if the function stack frame has a var-sized object. 
Also added a test case to check for the added benefit of this patch: it's optimizing away the unnecessary restore of sp from fp for some non-leaf functions.

Jakob Stoklund Olesen 53c5022040 Implement register class inflation. 
When splitting a live range, the new registers have fewer uses and the
permissible register class may be less constrained. Recompute the register class
constraint from the uses of new registers created for a split. This may let them
be allocated from a larger set, possibly avoiding a spill.
