patch 9.0.1842: Need more accurate profiling
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.
