Fix `str.replace_re` and `str.replace_re_all` (#6615)
Fixes #6057. The reductions of `str.replace_re` and `str.replace_re_all`
were not correctly enforcing that the operations replace the _first_
occurrence of some regular expression in a string. This commit fixes the
issue by introducing a new operator `str.indexof_re(s, r, n)`, which,
analoguously to `str.indexof`, returns the index of the first match of
the regular expression `r` in `s`. The commit adds basic rewrites for
evaluating the operator as well as its reduction. Additionally, it
converts the reductions of `str.replace_re` and `str.replace_re_all` to
use that new operator. This simplifies the reductions of the two
operators and ensures that the semantics are consistent between the two.
