For PR786:
...
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

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.
