Assume that we have isinf().
Windows has this, and so do all other live platforms according to the buildfarm, so remove the configure probe and src/port/ substitution. This also lets us get rid of some configure probes that existed only to support src/port/isinf.c. I kept the port.h hack to force using __builtin_isinf() on clang, though. This is part of a series of commits to get rid of no-longer-relevant configure checks and dead src/port/ code. I'm committing them separately to make it easier to back out individual changes if they prove less portable than I expect. Discussion: https://postgr.es/m/15379.1582221614@sss.pgh.pa.us
