Fixes texrect-many regression with ff_fragment_shader -- as we added
refs to the subsequent texcoord scaling paramters, the array got
realloced to a new address while our params[] still pointed at the old
location.
The driver was saying that independend blend functions was not supported,
but it really was. The driver was using the per-target independend blend
factors but the state tracker was only setting the 0th one (per the
Gallium spec).
Fixes a piglit fbo-drawbuffers2-blend regression.

The removed semantic check also exists in ast_type_specifier::hir(), which
is a more natural location for it.
The check verified that precision statements are applied only to types
float and int.
* Check that precision qualifiers only appear in language versions 1.00,
1.30, and later.
* Check that precision qualifiers do not apply to bools and structs.
Fixes the following Piglit tests:
* spec/glsl-1.30/precision-qualifiers/precision-bool-01.frag
* spec/glsl-1.30/precision-qualifiers/precision-struct-01.frag
* spec/glsl-1.30/precision-qualifiers/precision-struct-02.frag
Change default value to ast_precision_none, which denotes the absence of
a precision of a qualifier.
Previously, the default value was ast_precision_high. This made it
impossible to detect if a precision qualifier was present or not.
The check is performed only in GLSL versions >= 1.30.
From section 4.3.4 of the GLSL 1.30 spec:
"It is an error to use centroid in in a vertex shader."
Fixes Piglit test
spec/glsl-1.30/compiler/storage-qualifiers/vs-centroid-in-01.vert
The check is performed only in GLSL versions >= 1.30.
Fixes the following Piglit tests:
* spec/glsl-1.30/compiler/interpolation-qualifiers/fs-smooth-02.frag
* spec/glsl-1.30/compiler/interpolation-qualifiers/vs-smooth-01.vert
... and 'centroid varying'. The check is performed only in GLSL
versions >= 1.30.
From page 29 (page 35 of the PDF) of the GLSL 1.30 spec:
"interpolation qualifiers may only precede the qualifiers in, centroid
in, out, or centroid out in a declaration. They do not apply to the
deprecated storage qualifiers varying or centroid varying."
Fixes Piglit test
spec/glsl-1.30/compiler/interpolation-qualifiers/smooth-varying-01.frag.
If an interpolation qualifier is present, then the method returns that
qualifier's string representation. For example, if the noperspective bit
is set, then it returns "noperspective".
This implements the extension by choosing a different set of texture
fetch functions when the texture parameter changes.

If a literal slot isn't used it should be set
to 0 instead of an uninitialized value. Also the
channels for pre R700 trig functions were incorrect.
And most important literals were not counted against ndw,
resulting in an invalid force_add_cf detection.
