This avoids going through the wrapper that has to rewrite the data for
packed depth/stencil. This isn't done in _swrast_read_stencil_span
because we don't want to map/unmap for each span.

i965's MUL instruction can't take an immediate value as its first
argument. So normally, if constant propagation wants to propagate a
constant into the first argument of a MUL instruction, it swaps the
order of the two arguments.
This doesn't work for 32-bit integer (and unsigned integer)
multiplies, because the MUL operation is asymmetric in that case (it
multiplies 16 bits of one operand by 32 bits of the other).
Fixes piglit tests {vs,fs}-multiply-const-{ivec4,uvec4}.

If we're drawing sprites and the fragment shader needs both auto-
generated texcoords and user-defined varying vars we need to use
this fallback path.
The reason is when we enable auto texcoord generation, it gets
enabled for all texcoord sets. And that clobbers the user-defined
varying vars.

If we use the draw-module for wide point/line/etc drawing we'll need
a fragment shader too (like we pass in the vertex shader).

The state tracker may generate shaders that use generic vs outputs /
fs inputs like:
DCL IN[0], GENERIC[0]
DCL IN[1], GENERIC[10]
DCL IN[2], GENERIC[11]
This patch remaps 0, 10, 11 to small integers like 1, 2, 3 so that we
stay inside the SVGA3D limit (8).
The remapping is done to both the vertex shader outputs and the
fragment shader inputs. The same mapping must be used for a vs/fs
pair.
Note that 'union svga_compile_key' is now 'struct svga_compile_key'
because we needed to add the register remapping table. The change in
size isn't really significant though (it's not a search key).
Also, add assertions when building up SVGA3D src/dst registers to we
don't try to store too large of value for the bitfield size.

The returned value should be a texture target index, not a bit.
I spotted this from seeing a new compiler warning caused by the increase
in the number of texture targets. This has been broken for a long time.

This requires tracking a couple extra fields in ir_variable:
* A flag to indicate that a variable had an initializer.
* For non-const variables, a field to track the constant value of the
variable's initializer.
For variables non-constant initalizers, ir_variable::has_initializer
will be true, but ir_variable::constant_initializer will be NULL. The
linker can use the values of these fields to check adherence to the
GLSL 4.20 rules for shared global variables:
"If a shared global has multiple initializers, the initializers
must all be constant expressions, and they must all have the same
value. Otherwise, a link error will result. (A shared global
having only one initializer does not require that initializer to
be a constant expression.)"
Previous to 4.20 the GLSL spec simply said that initializers must have
the same value. In this case of non-constant initializers, this was
impossible to determine. As a result, no vendor actually implemented
that behavior. The 4.20 behavior matches the behavior of NVIDIA's
shipping implementations.
NOTE: This is candidate for the 7.11 branch. This patch also needs
the preceding patch "glsl: Refactor generate_ARB_draw_buffers_variables
to use add_builtin_constant"
