Right now libglsl.la depends on libnir.la so putting it in libnir.la
adds a dependency on libglsl.la that goes the wrong direction.

Split standalone glsl_compiler into a libstandalone.la and a thin
main.cpp. This way drivers can re-use the glsl standalone frontend in
their own standalone compilers.

nir_lower_wpos_ytransform() is great for OpenGL, which allows
applications to choose whether their coordinate system's origin is
upper left/lower left, and whether the pixel center should be on
integer/half-integer boundaries.
Vulkan, however, has much simpler requirements: the pixel center
is always half-integer, and the origin is always upper left. No
coordinate transform is needed - we just need to add <0.5, 0.5>.
This means that we can avoid using (and setting up) a uniform.
I thought about adding more options to nir_lower_wpos_ytransform(),
but making a new pass that never even touched uniforms seemed simpler.
v2: Use normal iterator rather than _safe variant (noticed by Matt).

This just renames the file in anticipation of adding cull lowering,
and renames the internals.

Since it will gain support to lower inputs, give it a more generic name.

A pass to lower complex (struct/array/mat) inputs/outputs to primitive
types. This allows, for example, linking that removes unused components
of a larger type which is not indirectly accessed.
In the near term, it is needed for gallium (mesa/st) support for NIR,
since only used components of a type are assigned VBO slots, and we
otherwise have no way to represent that to the driver backend. But it
should be useful for doing shader linking in NIR.
v2: use glsl_count_attribute_slots() rather than passing a type_size
fxn pointer

While it does rely on NIR, it's not really part of the NIR core. At the
moment, it still builds as part of libnir but that can be changed later if
desired.

This commit adds a NIR pass for lowering away returns in functions. If the
return is in a loop, it is lowered to a break. If it is not in a loop,
it's lowered away by moving/deleting code as needed.

Right now, we have phi placement code in two places and there are other
places where it would be nice to be able to do this analysis. Instead of
repeating it all over the place, this commit adds a helper for placing all
of the needed phi nodes for a value.

This new pass lowers load/store_var intrinsics that act on indirect derefs
to if-ladder of direct load/store_var intrinsics. The if-ladders perform a
simple binary search on the indirect.

Currently it's an empty library, although it'll be used to store common
code between GLSL and NIR that is compiler specific (rather than generic
as the one in src/util).
XXX: strictly speaking we could add a python/mako parser to generate the
relevant files instead including builtin_type_macros.h in such a manner.
