Fix ldbl-128ibm expl overflow in non-default rounding modes (bug 19078).
The ldbl-128ibm expl wrapper checks the argument to determine when to call __kernel_standard_l, thereby overriding overflowing results from __ieee754_expl that could otherwise (given appropriately patched libgcc) be correct for the rounding mode. This patch changes it to check the result of __ieee754_expl instead, as other versions of this wrapper do. Tested for powerpc. [BZ #19078] * sysdeps/ieee754/ldbl-128ibm/w_expl.c (o_thres): Remove variable. (u_thres): Likewise. (__expl): Determine whether to call __kernel_standard_l based on value of result, not argument.
