Fix a nasty miscompilation of 176.gcc on linux/x86 where we synthesized
a memset using 16-byte XMM stores, but where the stack realignment code
didn't work. Until it does (PR2962) disable use of xmm regs in memcpy
and memset formation for linux and other targets with insufficiently
aligned stacks.
This is part of PR2888

remove v[if]cmp functionality from the 2.4 release. These instructions will be removed or substantially changes in mainline after the 2.4 release and we don't want to have to support these for backwards compatibility purposes.

Also update sub-register intervals after a trivial computation is rematt'ed
for a copy instruction. PR2775.

Change CALLSEQ_BEGIN and CALLSEQ_END to take TargetConstant's as
parameters instead of raw Constants. This prevents the constants from
being selected by the isel pass, fixing PR2735.

are Inexact. (These are not Inexact as defined
by IEEE754, but that seems like a reasonable way
to abstract what happens: information is lost.)

Fix a bug in the local allocator's liveness computation where it2008-10-04T00:31:14ZDan Gohmangohman@apple.com2008-10-04T00:31:14Zurn:sha1:022b21ff7c047f8c1615a6588052c55427bcd9b0
was setting kill flags on tied uses in two-address instructions.
The kill flags were causing the allocator to think it could
allocate the use and its tied def in different registers.
