History
Joseph Myers 7abf97bed9 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.

	* include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ &&
	__FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (trunc): Redirect
	using MATH_REDIRECT.
	* sysdeps/aarch64/fpu/s_trunc.c: Define NO_MATH_REDIRECT before
	header inclusion.
	* sysdeps/aarch64/fpu/s_truncf.c: Likewise.

	(ceil): Redirect to __ceil.
	(floor): Redirect to __floor.

	(__truncl): Call trunc instead of __trunc.
	* sysdeps/powerpc/fpu/math_private.h [_ARCH_PWR5X] (__trunc):
