second patch attempt, modifying widen_mult tree pass
This removes about 100 lines from expr.c, and adds about 90 lines to
tree-ssa-math, plus unfortunately infrastructure for the new tree codes
WIDEN_MULT_{PLUS,MINUS}_EXPR which is about 70 lines. It works for simple
testcases. Needs a more thorough test.
