Log message:
Add kernel support for the VFP FPU/SIMD unit. Based on a diff by drahn@.
This allows us to use floating-pointer and vector instructions in userland
code. The current implementation assumes all 32 VFP registers are present.
This should be the case on all armv7 hardware currently supported by
OpenBSD.
