fold-const.c (fold <PLUS_EXPR>): Transform x+x into x*2.0.
* fold-const.c (fold <PLUS_EXPR>): Transform x+x into x*2.0.
Optimize x*c+x and x+x*c into x*(c+1) and x*c1+x*c2 into x*(c1+c2)
for floating point expressions with -ffast-math.
(fold <MULT_EXPR>): Don't transform x*2.0 into x+x.
* expmed.c (expand_mult): Wrap long line. Expand x*2.0 as x+x.
* gcc.dg/20030804-1.c: New test case.
