error_parseis a non-reserved identifier that is not used by the standard library. I think it's better to remove its use. Perhaps it would also be better to removeerror_syntax, but see #438.Per [re.regex.construct]/6, the call to the pointer-size constructor of
basic_regexshould be well-defined whenpis null andlenis0. This PR makes such case accepted and makes some UB case diagnosed with_STL_VERIFY.Drive-by: Strengthening exception specification of
regex_error::code.
