[PATCH 3/3] gimple: allow more folding of memcpy [PR102125]

The current restriction on folding memcpy to a single element of size MOVE_MAX is excessively cautious on most machines and limits some significant further optimizations. So relax the restriction provided the copy size does not exceed MOVE_MAX * MOVE_RATIO and that a SET insn exists for moving th
