[3.6] bpo-31373: remove overly strict float range checks (GH-3486) (#3495)
This undoes a853a8ba7850381d49b284295dd6f0dc491dbe44 except for the pytime.c
parts. We want to continue to allow IEEE 754 doubles larger than FLT_MAX to be
rounded into finite floats. Tests were added to very this behavior.
(cherry picked from commit 2bb69a5b4e7f96cb35d1b28aa7b7b3974b351f59)
