Add new templates for IEEE wrappers

Several wrappers for IEEE functions use _LIB_VERSION / matherr /
__kernel_standard functionality, which we want to obsolete.  New
wrappers, such as for float128, must not use this functionality.

This patch adds new wrappers that only __set_errno and can be used by
the new float128 wrappers.

Tested for powerpc64le.

	* math/Makefile: Add wrappers to gen-libm-calls.
	* math/w_acos_template.c: New file.
	* math/w_acosh_template.c: Likewise.
