Remove unnecessary TYPECACHE_GT_OPR lookup

Browse Source 
The TYPECACHE_GT_OPR is not needed (it used to be in older version of
the MCV code), but the compiler failed to detect this as the result was
used in a fmgr_info() call, populating a FmgrInfo entry.

Backpatch to v12, where this code was introduced.
