Use trunc functions not __trunc 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 __trunc functions to call the
corresponding trunc names instead, with asm redirection to __trunc
when the calls are not inlined.
Tested for x86_64, and with build-many-glibcs.py.
