PATCH: Handle TARGET_96_ROUND_53_LONG_DOUBLE

[Loren James Rittle]

This patch kills another 8 gratitious FAILs for
TARGET_96_ROUND_53_LONG_DOUBLE targets (of which, only
i386-unknown-freebsd* is publicly known).

OK, to commit?

On a related note: I think, but am not yet sure, that
gcc.c-torture/execute/conversion.c is failing the 2 sub-tests [as
noted in http://gcc.gnu.org/ml/gcc-bugs/2009-09/msg02378.html] because
sizeof (long long) is greater than LDBL_MANT_DIG (and the test
actually assumes otherwise).  Does that sound right?

Loren
