* tree-optimize.c (execute_fixup_cfg): Likewise.
* builtins.c (avoid_folding_inline_builtin): New function.
(fold_call_expr): Don't optimize always_inline builtins before
inlining.
(fold_call_stmt): Likewise.
(fold_builtin_call_array): Likewise. Don't call
fold_builtin_varargs for BUILT_IN_MD builtins.
* gcc.dg/memset-1.c: New test.
