The SelectionDAGBuilder was promoting vector kernel arguments to legal
types, but this won't work for R600 and SI since kernel arguments are
stored in memory and can't be promoted. In order to handle vector
arguments correctly we need to look at the original types from the LLVM IR
function.

For _XYZ, the type of VDATA is v4i32, because v3i32 doesn't exist.
The ADDR64 bit is not exposed. A simpler intrinsic that doesn't take
a resource descriptor might be nicer.
The maximum number of input SGPRs is bumped to 17.

* Added R600_Reg64 class
* Added T#Index#.XY registers definition
* Added v2i32 register reads from parameter and global space
* Added f32 and i32 elements extraction from v2f32 and v2i32
* Added v2i32 -> v2f32 conversions

- Mark vec2 operations as expand. The addition of a vec2 register
class made them all legal.

A side-effect of this is that now the compiler expects kernel arguments
to be 4-byte aligned.
