* simplify-rtx.c (associative_constant_p): New function to test
whether an RTX expression is an immediate constant.
(simplify_associative_operation): New function to perform some
reassociation optimizations of associative binary expressions.
(simplify_binary_operation): Use simplify_associative_operation
to simplify PLUS, MULT, AND, IOR, XOR, SMIN, SMAX, UMIN and UMAX.
Floating point expressions are only reassociated when unsafe
math optimizations are permitted.
