Improve libm-test XFAILing for ibm128-libgcc.
This patch further improves XFAILing for ibm128-libgcc of tests in
auto-libm-test-*.
The bulk of the cases needing XFAILing are
xfail-rounding:ibm128-libgcc used for inputs where (possibly after
rounding the inputs to another floating-point type) the result
overflows (and the result in non-default rounding modes may be wildly
wrong with unpatched libgcc) or underflows near 0 (and the result in
non-default rounding modes may end up having the wrong sign). This
patch makes gen-auto-libm-tests detect such cases and apply
xfail-rounding:ibm128-libgcc automatically to them, so most of the
manual XFAILs in auto-libm-test-in are no longer needed (some are
still needed if e.g. the result is very close to overflow, resulting
in an internal overflow in libgcc in some rounding modes). A few
manual XFAILs are added for cases not covered by this
gen-auto-libm-tests change, and a few existing such XFAILs are left
in.
Tested for powerpc.
* math/gen-auto-libm-tests.c (output_for_one_input_case): Apply
xfail-rounding:ibm128-libgcc automatically to tests overflowing
and those that can underflow to zero.
* math/auto-libm-test-in: Remove most XFAILs for ibm128-libgcc and
add others.
* math/auto-libm-test-out: Regenerated.
