[X86] Remove override of shouldUseStrictFP_TO_INT for fp80. NFC
I suspect this became unnecessary after r354161. Prior to that
we may have been going through the default expansion of FP_TO_UINT
on 64-bit targets and then ending up back in Custom X86 handling
to handle the FP_TO_SINT for it. Now we just Custom handle the
FP_TO_UINT directly. We already need to handle it for 32-bit mode
during type legalization so we wouldn't save any code by using
the default expansion on 64-bit.
