* builtins.c (expand_builtin_strcmp): Defend against the possibility
that gen_cmpstrsi may fail: Stabilize the argument list against
re-evaluation and expand the library call directly using this saved
argument list if a cmpstrsi sequence can't be generated.
(expand_builtin_strncmp): Likewise.
* config/i386/i386.md (cmpstrsi, movstrsi): Disable with -Os.
* gcc.c-torture/execute/string-opt-8.c: Don't test optimizations
that inline strncmp as cmpstrsi on i386 when compiled with -Os.
