The fp-int-convert tests are meant to be correct independent of the sizes
involved, so this change is inappropriate and may point to a bug
elsewhere. Note that there are tests of conversion between long long and
float (and between TImode and float where TImode is supported). The only
case these tests don't handle is inexact conversions to/from non-IEEE
types (IBM long double), hence the conditional in fp-int-convert-timode.c
on LDBL_MANT_DIG != 106.
