Replace opr_sanity test's binary_coercible() function with C code.
opr_sanity's binary_coercible() function has always been meantto match the parser's notion of binary coercibility, but it alsohas always been a rather poor approximation of the parser'sreal rules (as embodied in IsBinaryCoercible()). That hasn'tbit us so far, but it's predictable that it will eventually.It also now emerges that implementing this check in plpgsqlperforms absolutely horribly in clobber-cache-always testing.(Perhaps we could do something about that, but I suspect it justmeans that plpgsql is exploiting catalog caching to the hilt.)Hence, let's replace binary_coercible() with a C shim that directlyinvokes IsBinaryCoercible(), eliminating both the semantic hazardand the performance issue.Most of regress.c's C functions are declared in create_function_1,but we can't simply move that to before opr_sanity/type_sanitysince those tests would complain about the resulting shell types.I chose to split it into create_function_0 and create_function_1.Since create_function_0 now runs as part of a parallel group whilecreate_function_1 doesn't, reduce the latter to create just thosefunctions that opr_sanity and type_sanity would whine about.To make room for create_function_0 in the second parallel groupof tests, move tstypes to the third parallel group.In passing, clean up some ordering deviations betweenparallel_schedule and serial_schedule.Discussion:https://postgr.es/m/292305.1620503097@sss.pgh.pa.us
