To able to move PHI-OPT's abs_replacement to match.pd, a bunch
of support needed to be added to PHI-OPT.
This is a set of 7 patches which allows us to remove abs_replacement
and even does one set further and does a few extra transformations
that abs_replacement did not do (just because of the moving from
fold to match).
Andrew Pinski (7):
Expand the comparison argument of fold_cond_expr_with_comparison
Reset the range info on the moved instruction in PHIOPT
Duplicate the range information of the phi onto the new ssa_name
Allow match-and-simplified phiopt to run in early phiopt
Try inverted comparison for match_simplify in phiopt
Lower for loops before lowering cond in genmatch
Port most of the A CMP 0 ? A : -A to match
