Fix i386 FP_TRAPPING_EXCEPTIONS.
The i386 sfp-machine.h defines FP_TRAPPING_EXCEPTIONS in a way that is
always wrong: it treats a set bit as indicating the exception is
trapping, when actually a set bit (both for 387 and SSE floating
point) indicates it is masked, and a clear bit indicates it is
trapping. This patch fixes this bug.
Bootstrapped with no regressions on x86_64-unknown-linux-gnu.
libgcc:
* config/i386/sfp-machine.h (FP_TRAPPING_EXCEPTIONS): Treat clear
bits not set bits as indicating trapping exceptions.
gcc/testsuite:
* gcc.dg/torture/float128-exact-underflow.c: New test.
