Missing Regex function

[regener]

So I was browsing the functions on the API site when I faced this, regex_match claims this:
If you intend on using the same regular expression pattern
multiple times, consider using regex_compile and regex_match_ex
instead of making this function reparse the expression each time.

There comes the "but" part, when I realized that regex_match_ex does not exist, not even in the module.cpp.

It is also mentioned at the description of regex_match_all.

Futhermore take a look at this: regex_split

Looks like doc needs to be updated. This function has been removed at some point because being redundant: 287f471.
