sparc64 passes floating point values in the floating point registers.
As the the generic ceil, floor and trunc functions use integer
instructions, it makes sense to provide a VIS3 version consisting in
the the generic version compiled with -mvis3. GCC will then use
movdtox, movxtod, movwtos and movstow instructions.

sparc32 passes the floating point values in the integer registers, so it
doesn't make sense to do the same.

Changelog:
	* sysdeps/ieee754/dbl-64/s_trunc.c: Avoid alias renamed.

	s_truncf-vis3, s_trunc-vis3.
