re PR middle-end/28283 (SuperH: Very unoptimal code generated for 64-bit ints)
PR middle-end/28283
* expmed.c (expand_shift): Additionally check that the shift_cost
is not MAX_COST and that INTVAL(op1) is less than MAX_BITS_PER_WORD
before implementing a LSHIFT_EXPR as a sequence of additions.
* config/sh/sh.c (shift_costs): Return MAX_COST to inform the
middle-end that DImode shifts need to be synthesized by expand.
