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.

Special case tblgen generated code for patterns like (and X, 255) or (or X, 42).
The dag/inst combiners often 'simplify' the masked value based on whether
or not the bits are live or known zero/one. This is good and dandy, but
often causes special case patterns to fail, such as alpha's CMPBGE pattern,
which looks like "(set GPRC:$RC, (setuge (and GPRC:$RA, 255), (and GPRC:$RB, 255)))".
Here the pattern for (and X, 255) should match actual dags like (and X, 254) if
the dag combiner proved that the missing bits are already zero (one for 'or').
For CodeGen/Alpha/cmpbge.ll:test2 for example, this results in:
sll $16,1,$0
cmpbge $0,$17,$0
ret $31,($26),1
instead of:
sll $16,1,$0
and $0,254,$0
and $17,255,$1
cmpule $1,$0,$0
ret $31,($26),1
