re PR middle-end/27567 (__builtin_memcpy generates redundant stores/moves.)
PR middle-end/27567
* builtins.c (fold_builtin_memcpy, fold_builtin_memmove): Remove.
(fold_builtin_mempcpy): Rename to...
(fold_builtin_memory_op): ... this. Optimize one element copy
into an assignment.
(fold_builtin_memset, fold_builtin_bzero, fold_builtin_bcopy): New
functions.
(expand_builtin_strcpy, expand_builtin_strncpy): Handle COMPOUND_EXPR.
(expand_builtin_memcpy, expand_builtin_mempcpy,
expand_builtin_memmove): Likewise. Use fold_builtin_memory_op.
(fold_builtin_1): Handle BUILT_IN_MEMSET, BUILT_IN_BZERO and
BUILT_IN_BCOPY. Use fold_builtin_memory_op for
BUILT_IN_MEM{CPY,PCPY,MOVE}.
