Wrong type inference non-falsy-string for preg_match group containing start/end meta characters #12297
Description
Bug report
When a preg_match group contains ^ or $, the type of the group in the matches result array is inferred as non-falsy-string, indicating that it cannot be string '0'. That is wrong.
