Herald added a project: LLVM.

This adds support for the floor/ceil/trunc/... series of instructions, converting to various forms of VRINT. They use the same suffixes as the floating point counterparts do. There is not VTINTR, so nearbyint is expanded.

Also added a copysign test, to show it is expanded.
