* simplify-rtx.c (comparison_result): New.
(simplify_const_relational_operation): Use it instead of the five
"equal|op[01]ltu?" variables; consequently remove redundant "else"s.
Improve bounds-checking optimizations; remove subsumed POPCOUNT
optimizations. Extract nonzero_address_p optimizations into a
separate "if" together with optimizations where op1 is const0_rtx.
Optimize comparing an IOR with zero. Simplify op0 RELOP op0 for
floating-point arguments too when appropriate. Hoist test for ABS
outside the final switch statement.
* cse.c (fold_rtx): Don't look for an IOR equivalent of
folded_arg0 if we found a constant equivalent. Remove
transformations done in simplify-rtx.c for "op0 RELOP op0".
