Use ceil functions not __ceil functions in glibc libm.
Continuing the move to use, within libm, public names for libm
functions that can be inlined as built-in functions on many
architectures, this patch moves calls to __ceil functions to call the
corresponding ceil names instead, with asm redirection to __ceil when
the calls are not inlined.
Tested for x86_64, and with build-many-glibcs.py.
