Fix x86 / x86_64 expl, exp10l missing underflows (bug 16361).
Similar to various other bugs in this area, the x86 and x86_64 implementations of expl / exp10l can fail to produce underflow exceptions when the unscaled result has trailing 0 bits so the scaling down to subnormal precision is exact. This patch fixes this by forcing the exception in the case of tiny results. Tested for x86_64 and x86. [BZ #16361] * sysdeps/i386/fpu/e_expl.S [!USE_AS_EXPM1L] (cmin): New object. [!USE_AS_EXPM1L] (IEEE754_EXPL): Force underflow exception for tiny results. * sysdeps/x86_64/fpu/e_expl.S [!USE_AS_EXPM1L] (cmin): New object. [!USE_AS_EXPM1L] (IEEE754_EXPL): Force underflow exception for tiny results. * math/auto-libm-test-in: Add more tests of exp and exp10. Do not mark underflow exceptions as possibly missing for bug 16361. * math/auto-libm-test-out: Regenerated.
