[AArch64] Fix PR81800

PR81800 is about the lrint inline giving spurious FE_INEXACT exceptions.
The previous change for PR81800 didn't fix this: when lrint is disabled
in the backend, the midend will simply use llrint.  This actually makes
things worse since llrint now also ignores FE_INVALID exceptions!
The fix is to disable lrint/llrint on double if the size of a long is
smaller (ie. ilp32).

	operand is larger than a long int.
