Remove lc_ctype_is_c().

Browse Source 
Instead always fetch the locale and look at the ctype_is_c field.

hba.c relies on regexes working for the C locale without needing
catalog access, which worked before due to a special case for
C_COLLATION_OID in lc_ctype_is_c(). Move the special case to
pg_set_regex_collation() now that lc_ctype_is_c() is gone.
