* fold-const.c (fold <MULT_EXPR>): Optimize (C1/X)*C2 into
(C1*C2)/X when unsafe math optimizations are allowed.
(fold <RDIV_EXPR>): Optimize C1/(X*C2) into (C1/C2)/X with unsafe
math optimizations.  Minor code clean-ups.  Recursively call
fold when constructing sub-expressions.

* gcc.dg/20030826-1.c: New test case.
