Add SPIRV intrinsics for ShaderExecutionReordering and RW/Buffer. (#3252)

* Add SPIRV intrinsics for ShaderExecutionReordering.

* Add intrinsics for `Buffer` and `RWBuffer`.

* Various spirv fixes.

* Marshal bool vector type.

* Inline global constants + OpFOrdNotEqual->OpFUnordNotEqual.

* Fix.
