When tailcallopt is enabled all fastcc calls must have an aligned argument stack size. Add a test case.

Fix PR2748. Avoid coalescing physical register with virtual register which would create illegal extract_subreg. e.g.
vr1024 = extract_subreg vr1025, 1
...
vr1024 = mov8rr AH
If vr1024 is coalesced with AH, the extract_subreg is now illegal since AH does not have a super-reg whose sub-register 1 is AH.

by its first field, but TableGen doesn't actually enforce creating it that 
way. TableGen sorts the records that will be used to create it by the names 
of the records, not the Name field of those records.

This patch corrects the sort to use the "Name" field of the record as the 
sort key.

Change getSubReg semantics. It now returns zero if the specified register doesn't have a subreg of the specified index.

cmp-and-swap reversed the Cmp and Swap arguments; comments
make it clear this is unintentional.  Unfortunately, the
x86 BE had a compensating reversal, which is removed here.
PPC is OK.

From inspection of the Alpha code I think it is OK, but
if somebody has that platform please check it out.  I
cannot test on that platform.

If ISD::ANY_EXTEND fails, try ISD::ZERO_EXTEND and ISD::SIGN_EXTEND before giving up.  This fixes 445.gobmk on

Fix a bug in the coalescer where it didn't check if a live interval existed before trying to manipulate it.  This
was exposed by fast isel's handling of shifts on X86-64.  With this, FreeBench/pcompress2 passes on X86-64 in fast isel.
