glsl: Fix aggregates with dynamic initializers.

Vectors are falling in to the ir_dereference_array() path.

Without this change, the following glsl aborts the debug driver,
or gets the wrong answer in release:

mat2x2 a = mat2( vec2( 1.0, vertex.x ), vec2( 0.0, 1.0 ) );

Also submitting piglit tests, will reference in bug.

v2: Rebase on Mesa master.

v3: Remove unneeded check for arrays, which are covered by
    process_array_constructor(), recommended by Timothy Arceri.
