nir: Add a "compact array" flag and IO lowering code.
Certain built-in arrays, such as gl_ClipDistance[], gl_CullDistance[],
gl_TessLevelInner[], and gl_TessLevelOuter[] are specified as scalar
arrays. Normal scalar arrays are sparse - each array element usually
occupies a whole vec4 slot. However, most hardware assumes these
built-in arrays are tightly packed.
The new var->data.compact flag indicates that a scalar array should
be tightly packed, so a float[4] array would take up a single vec4
slot, and a float[8] array would take up two slots.
They are still arrays, not vec4s, however. nir_lower_io will generate
intrinsics using ARB_enhanced_layouts style component qualifiers.
v2: Add nir_validate code to enforce type restrictions.
