Correct IBM long double frexpl.
Besides fixing the bugzilla, this also fixes corner-cases where the high and low double differ greatly in magnitude, and handles a denormal input without resorting to a fp rescale. [BZ #16740] [BZ #16619] * sysdeps/ieee754/ldbl-128ibm/s_frexpl.c (__frexpl): Rewrite. * math/libm-test.inc (frexp_test_data): Add tests.
