re PR rtl-optimization/17236 (inefficient code for long long multiply on x86)
PR rtl-optimization/17236
* optabs.c (expand_doubleword_mult): New helper function split out
from expand_binop. Permute the order in which instructions are
emitted to minimize the number of simultaneously live registers.
(expand_binop): Call expand_doubleword_mult to synthesize a double
word multiplication.
