Add an int64_t variant of abs, for host environments
...
without one. Use it where we were using abs on
int64_t objects.
(I strongly suspect the casts to unsigned in the
fragments in LoopStrengthReduce are not doing whatever
the original intent was, but the obvious change to
uint64_t doesn't work. Maybe later.)

Change the 'isStore' inferrer to look for 'SDNPMayStore'
...
instead of "ISD::STORE". This allows us to mark target-specific dag
nodes as storing (such as ppc byteswap stores). This allows us to remove
more explicit isStore flags from the .td files.
Finally, add a warning for when a .td file contains an explicit
isStore and tblgen is able to infer it.

Unify CALLSEQ_{START,END}. They take 4 parameters: the chain, two stack
...
adjustment fields, and an optional flag. If there is a "dynamic_stackalloc" in
the code, make sure that it's bracketed by CALLSEQ_START and CALLSEQ_END. If
not, then there is the potential for the stack to be changed while the stack's
being used by another instruction (like a call).
This can only result in tears...

Use cute tblgen tricks to make zap handling more powerful. Specifically,
...
when the dag combiner simplifies an and mask, notice this and allow those bits
to be missing from the zap mask.
This compiles Alpha/zapnot4.ll into:
sll $16,3,$0
zapnot $0,3,$0
ret $31,($26),1
instead of:
ldah $0,1($31)
lda $0,-8($0)
sll $16,3,$1
and $1,$0,$0
ret $31,($26),1
It would be *really* nice to replace the hunk of code in the
AlphaISelDAGToDAG.cpp file that matches (and (srl (x, C), c2) into
(SRL (ZAPNOTi)) with a similar pattern, but I've spent enough time poking
at alpha. Make andrew will do this.
