i965: Add support for integral vertex attributes.
When a vertex shader input attribute is declared with an integral type
(e.g. ivec4), we need to ensure that the generated vertex shader code
addresses the vertex attribute register using the proper register
type. (Previously, we assumed all vertex shader input attributes were
floating-point).
In addition, when uploading vertex data that was specified with
VertexAttribIPointer, we need to instruct the vertex fetch unit to
convert the data to signed or unsigned int, rather than float. And
when filling in the implied w=1 on a vector with less than 4
components, we need to fill it in with the integer representation of 1
rather than the floating-point representation of 1.

mesa: Add glsl_type::get_scalar_type() function.
This function is similar to get_base_type(), but when called on
arrays, it returns the scalar type composing the array. For example,
glsl_type(vec4[]) => float_type.

i965/gen6+: Switch GLSL from ALT to IEEE floating point mode
i965 graphics hardware has two floating point modes: ALT and IEEE. In
ALT mode, floating-point operations never generate infinities or NaNs,
and MOV instructions translate infinities and NaNs to finite values.
In IEEE mode, infinities and NaNs behave as specified in the IEEE 754
spec.
Previously, we used ALT mode for all vertex and fragment programs,
whether they were GLSL programs or ARB programs. The GLSL spec is
sufficiently vague about how infs and nans are to be handled that it
was unclear whether this mode was compliant with the GLSL 1.30 spec or
not, and it made it very difficult to test the isinf() and isnan()
functions.
This patch changes i965 GLSL programs to use IEEE floating-point mode,
which is clearly compliant with GLSL 1.30's inf/nan requirements. In
addition to making the Piglit isinf and isnan tests pass, this paves
the way for future support of the ARB_shader_precision extension.
Unfortunately we still have to use ALT floating-point mode when
executing ARB programs, because those programs require 0^0 == 1, and
i965 hardware generates 0^0 == NaN in IEEE mode.
Fixes piglit tests "isinf-and-isnan fs_fbo", "isinf-and-isnan vs_fbo",
and {fs,vs}-{isinf,isnan}-{vec2,vec3,vec4}.

glsl: Add isinf() and isnan() builtins.
The implementations are as follows:
isinf(x) = (abs(x) == +infinity)
isnan(x) = (x != x)
Note: the latter formula is not necessarily obvious. It works because
NaN is the only floating point number that does not equal itself.
Fixes piglit tests "isinf-and-isnan fs_basic" and "isinf-and-isnan
vs_basic".

glsl: Add '.ir' extension to builtin IR files
This patch adds the extension '.ir' to all the files in
src/glsl/builtins/ir/, and changes generate_builtins.py so that it no
longer globs on '*' to find the files to build. This prevents
spurious files (such as EMACS' infamous *~ backup files) from breaking
the build.

glsl: Fix copy-paste error in constant_expression_value(ir_binop_nequal)
The implementation of ir_binop_nequal in constant_expression_value()
appears to have been copy-and-pasted from the implementation of
ir_binop_equal, but with all instances of '==' changed to '!='. This
is correct except for one minor flaw: one of those '==' operators was
in an assertion checking that the types of the two arguments were
equal. That one needs to stay an '=='.
