Dawid Jurczak 11338e998d [LoopIdiom] Transform memmove-like loop into memmove (PR46179) ...

The purpose of patch is to learn Loop idiom recognition pass how to recognize simple memmove patterns
in similar way like GCC: https://godbolt.org/z/fh95e83od
LoopIdiomRecognize already has machinery for memset and memcpy recognition, patch tries to extend exisiting capabilities with minimal effort.
