0650cceb38 Add a separate ARM instruction format for Saturate instructions. 
(I discovered 2 more copies of the ARM instruction format list, bringing the
total to 4!!  Two of them were already out of sync.  I haven't yet gotten into
the disassembler enough to know the best way to fix this, but something needs
to be done.)  Add support for encoding these instructions.

32d28f5432 Avoid multiple definition warnings when both config.h and 
llvm-config.h are included.

This is the cmake counterpart of r110547. See bug #7809.

6eb24fd744 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.

a095d3fe73 Now that we're using ConstantRange to represent potential values, make use of that represenation to 
create constraints from comparisons other than eq/neq.

713062e756 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.

e0262a6e24 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".

6036d58c40 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.

d9a1b0d046 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.

245a1faf76 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.

3d47dbe761 Fix ARM hasFP() semantics. It should return true whenever FP register is 
reserved, not available for general allocation. This eliminates all the
extra checks for Darwin.

This change also fixes the use of FP to access frame indices in leaf
functions and cleaned up some confusing code in epilogue emission.
