Jason Ekstrand b3fd098e7d nir: Make bcsel a fully vector operation
Previously, the condition was a scalar that applied to all components
simultaneously.  As of this commit, the condition is a vector and each
component is switched seperately.

Jason Ekstrand b6c81b3ff4 nir/metadata: Rename metadata_dirty to metadata_preserve
nir_metadata_dirty was a terrible name because the parameter it takes is
the metadata to be preserved.  This is really confusing because it looks
like it's doing the opposite of what it is actually doing.  Now it's named
sensibly.

Jason Ekstrand 27663dbe8e nir: Vectorize intrinsics
We used to have the number of components built into the intrinsic.  This
meant that all of our load/store intrinsics had vec1, vec2, vec3, and vec4
variants.  This lead to piles of switch statements to generate the correct
intrinsic names, and introspection to figure out the number of components.
We can make things much nicer by allowing "vectorized" intrinsics.

Jason Ekstrand d477beab07 nir: Add a pass to lower local variable accesses to SSA values
This pass analizes all of the load/store operations and, when a variable is
never aliased (potentially used by an indirect operation), it is lowered
directly to an SSA value.  This pass translates to SSA directly and does
not require any fixup by the original to-SSA pass.
