patch 9.0.1842: Need more accurate profiling

Browse Source 
Problem:  Need more accurate profiling
Solution: Improve profiling results

closes: #12192

Reduce overhead of checking if a function should be profiled,
by caching results of checking (which are done with regexp).

Cache uf_hash for uf_name in ufunc_T.

Cache cleared when regexps are changed.

Break at first match for has_profiling lookup.
