i965/vs: Add support for splitting virtual GRFs.

This should improve our ability to register allocate without spilling.
Unfortuantely, due to the live variable analysis being ignorant of loops, we
still have register allocation failures on some programs.

v2: Add more context to the comment explaining the function.
