GLSL 1.30 states clearly that only float and int are allowed, while the
GLSL ES specification's issues section states that sampler types may
take precision qualifiers.
Fixes compilation failures in 3DMarkMobileES 2.0 and GLBenchmark 2.0.

Civilization 4's shaders make heavy use of gl_Color and don't use
perspective interpolation. This resulted in rivers, units, trees, and
so on being rendered almost entirely white. This is a regression
compared to the old fragment shader backend.
Found by inspection (comparing the old and new FS backend code).

ctx->dPriv might be != NULL then draw which is NULL is accessed:
struct dri_drawable *draw = dri_drawable(driDrawPriv);
[..]
if (ctx->dPriv != driDrawPriv) {
ctx->dPriv = driDrawPriv;
draw->texture_stamp = driDrawPriv->lastStamp - 1;

This is an awful hack and will hurt performance on Ironlake, but we're
at a loss as to what's going wrong otherwise. This is the only common
variable we've found that avoids the problem on 4 applications
(CelShading, gnome-shell, Pill Popper, and my GLSL demo), while other
variables we've tried appear to only be confounding. Neither the
specifications nor the hardware team have been able to provide any
enlightenment, despite much searching.

It should have been a tip when the spec says "However, implicitly

*initializers and assignments appear to have different semantics*."

The signature list in a function must contain only ir_function_signature nodes.
The target of an ir_call must be an ir_function_signature.
These were added while trying to debug Mesa bugzilla #34203.

If an array redeclaration includes an initializer, the initializer
would previously be dropped on the floor. Instead, directly apply the
initializer to the correct ir_variable instance and append the
generated instructions.

Some significant edits were made to this patch during cherry picking.
There some fairly major conflicts due to GLSL 1.30 features and
extensions added in master that do not exist in the 7.10 branch.

Previously, the rule deleted by this commit was matched every single
time (being the longest match). If not skipping, it used REJECT to
continue on to the actual correct rule.
The flex manual advises against using REJECT where possible, as it is
one of the most expensive lexer features. So using it on every match
seems undesirable. Perhaps more importantly, it made it necessary for
the #if directive rules to contain a look-ahead pattern to make them
as long as the (now deleted) "skip the whole line" rule.
This patch introduces an exclusive start state, SKIP, to avoid REJECTs.
Each time the lexer is called, the code at the top of the rules section
will run, implicitly switching the state to the correct one.
Fixes piglit tests 16384-consecutive-chars.frag and
16385-consecutive-chars.frag.

If two buffers had the same stride where one buffer is a user one and
the other is a vbo, it was considered to be one interleaved buffer,
resulting in incorrect rendering and crashes.
This patch makes sure that the interleaved buffer is either user or vbo,
not both.
