Fixing bug #5222 (anomaly with "`pat" in the presence of scope delimiters).
We seized this opportunity to factorize the code for interning `pat
with more general pre-existing code.
More precisely: There was already a function to compute the free
variables of a pattern. Commit c6d9d4fb rewrote an approximation of it
and #5222 hits cases non-treated by this function. We remove the
partially-defined redundant code and use instead the existing code
since intern_cases_pattern, already called, was already doing this
computation. (In doing so, we discover a bug in merging names in the
presence of nested "as" clauses, which we fix in previous
commit. Additionally, intern_local_pattern was misleadingly overkill
to simply mean a folding on Id.Set.add and we avoid the detour.
