Add Optimization keyword for param_max_inline_insns_auto param.
2019-11-14 Martin Liska <mliska@suse.cz>
* ipa-cp.c (devirtualization_time_bonus): Use opt_for_fn
of a callee to get value of the param.
* ipa-inline.c (inline_insns_auto): Use proper
opt_for_fn.
* opts.c (maybe_default_option): Do not overwrite param
value if optimization level does not match. Note that
params usually have default value set via Init() keyword.
* params.opt: Remove -param=max-inline-insns-auto-O2.
* cif-code.def (MAX_INLINE_INSNS_AUTO_O2_LIMIT): Remove.
* doc/invoke.texi: Remove documentation of
max-inline-insns-auto-O2.

* c-c++-common/asan/memcmp-1.c: Update expected backtrace.
