make any assumptions about when the two conditions will agree on when
to permit the loop to exit. This fixes PR7845.

9a1c189d9e 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.

045573ce21 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.

95743d8748 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.

b67b12ea64 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.

ac096808a3 Re-apply r110655 with fixes. Epilogue must restore sp from fp if the function stack frame has a var-sized object.

9db3ea46cb 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.
