re PR middle-end/18293 (Redundant copy operation introduced by expand)
PR middle-end/18293
* expmed.c (EXACT_POWER_OF_2_OR_ZERO_P): Move definition earlier.
(expand_mult): Special case powers of two to avoid synth_mult.
* loop.c (product_cheap_p): Handle case where expand_mult does
require/generate any instructions (i.e. multiplication by zero).
