Fix ldbl-128ibm ceill, floorl inlining of ceil, floor.
The ldbl-128ibm implementations of ceill and floorl call the corresponding double functions. This patch fixes those implementations to call those functions as ceil and floor rather than as __ceil and __floor, so that the proper inlining takes place when possible, while including local asm redirections for when the functions are not inlined since NO_MATH_REDIRECT applies to the double functions as well as to the long double ones. Tested with build-many-glibcs.py for all its powerpc configurations. * sysdeps/ieee754/ldbl-128ibm/s_ceill.c (ceil): Redirect to __ceil. (__ceill): Call ceil instead of __ceil. * sysdeps/ieee754/ldbl-128ibm/s_floorl.c (floor): Redirect to __floor. (__floorl): Call floor instead of __floor.
