Fix ldbl-128 lrintl, lroundl missing exceptions for 32-bit long (bug 19085).
The ldbl-128 implementations of lrintl and lroundl miss "invalid" exceptions on systems with 32-bit long for arguments that overflow long but have exponent below 48. This patch fixes this by rearranging the sequence of tests in the code so the exponent < 48 case is only used for exponents that don't overflow long. Tested for mips64 (n32 and n64). [BZ #19085] * sysdeps/ieee754/ldbl-128/s_lrintl.c (__lrintl): Move test for exponent below 48 inside case for non-overflowing exponent. * sysdeps/ieee754/ldbl-128/s_lroundl.c (__lroundl): Likewise.
