Replace opr_sanity test's binary_coercible() function with C code. opr_sanity's binary_coercible() function has always been meant to match the parser's notion of binary coercibility, but it also has always been a rather poor approximation of the parser's real rules (as embodied in IsBinaryCoercible()). That hasn't bit us so far, but it's predictable that it will eventually. It also now emerges that implementing this check in plpgsql performs absolutely horribly in clobber-cache-always testing. (Perhaps we could do something about that, but I suspect it just means that plpgsql is exploiting catalog caching to the hilt.) Hence, let's replace binary_coercible() with a C shim that directly invokes IsBinaryCoercible(), eliminating both the semantic hazard and 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_sanity since 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 while create_function_1 doesn't, reduce the latter to create just those functions that opr_sanity and type_sanity would whine about. To make room for create_function_0 in the second parallel group of tests, move tstypes to the third parallel group. In passing, clean up some ordering deviations between parallel_schedule and serial_schedule. Discussion: https://postgr.es/m/292305.1620503097@sss.pgh.pa.us
