Aurelien Jarno bdf20beac1 sparc64: add a VIS3 version of ceil, floor and trunc 
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.
