MDEV-7999 - PROFILING routines take 0.2% when profiling disabled
PROFILING::start_new_query() optimizations:
- no need to check "current": added assertion instead
- "enabled" now means "is enabled currently" instead of "was enabled at query
start". Old meaning was useless, new meaning echoes OPTION_PROFILING so
that start_new_query() can be defined in sql_profile.h.
- remnants of start_new_query() moved to sql_profile.h so it can be inlined
PROFILING::start_new_query() overhead dropped 0.08% -> out of radar.
PROFILING::set_query_source() optimizations:
- no need to check "enabled": !enabled && current is impossible
- remnants of set_query_source() moved to sql_profile.h so it can be inlined
PROFILING::set_query_source() overhead dropped 0.02% -> out of radar.
PROFILING::finish_current_query() optimizations:
- moved "current" check out to sql_profile.h so it can be inlined
PROFILING::finish_current_query() overhead dropped 0.10% -> out of radar.
