Do an ordinary assignment in STRICT_ASSIGN() except for floats until

there is a problem with non-floats (when i386 defaults to extra
precision).  This essentially restores yesterday's behaviour for doubles
on i386 (since generic rint() isn't used and everywhere else assumed
working assignment), but for arches that use the generic rint() it
finishes restoring some of 1995's behaviour (don't waste time doing
unnecessary store/load).
