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.
