glGetActiveUniform is not supposed to report block members that are not
active even if they are included in the layout of the block. The block
layout is determined from the GLSL_TYPE_INTERFACE that defines the
block, so eliminating the ir_variables that correspond to the individual
fields is safe.
Fixes gles3conform test
uniform_buffer_object_getuniformindices_for_for_nonexistent_or_not_active_uniform_names.
This also fixes the assertion failures (added in the previous commit) in
gles3conform uniform_buffer_object_index_of_not_active_block,
uniform_buffer_object_inherit_and_override_layouts, and
uniform_buffer_object_repeat_global_scope_layouts.

glGetUniformIndices requires that the block instance index not be
present in the name of queried uniforms. However,
gl_uniform_buffer_variable::Name will include the instance index. The
IndexName field is added to handle this difference.
Note that currently IndexName will always point to the same string as
Name. This will change soon.

Interfaces are structurally identical to structures from the compiler's
point of view. They have some additional restrictions, and generally
GPUs use different instructions to access them. Using a different base
type should make this a bit easier.
This commit also adds the glsl_type::interface_packing fields. For
GLSL_TYPE_INTERFACE types, this will track the specified packing mode.
It is analogous to gl_uniform_buffer::_Packing.
v2: Add serveral missing GLSL_TYPE_INTERFACE cases in switch-statements.

In GLSL ES 3.00 (and GLSL 1.50), uniform blocks can have an associated
"instance name", which essentially namespaces the variables inside.
This patch adds basic parsing for this new feature, but doesn't yet hook
it up to actually do anything yet.
It does not support for arrays of interface blocks; a later commit will
take care of that.
This change temporarily regresses the piglit test
interface-name-access-without-interface-name.vert. This shader failed
to compile before (the expected result), but it failed to compile for
the wrong reason. This is not a real regression.

The existing code has a lot of duplication; the only difference between
the two cases is whether we merge in an additional layout qualifier.
Apparently creating a layout_qualifieropt rule that can be empty causes
a lot of conflicts and confusion. However, refactoring out the guts of
the ast_uniform_block creation works fine.

Also slightly change the compatibility test. Instead of comparing the
offsets of the block variables, compare the packing mode of the blocks.
Ideally we don't want to assign the offsets until a later stage of

This makes it easier to find switch-statements that need to be updated
after a new GLSL_TYPE_* is added because the compiler will generate a
warning.
Switch-statements that only had a small number of cases (e.g.,
everything in ir_constant_expression.cpp) were not modified. I may
regret that decision when we eventually add support for doubles.
