a80cbd6d82 Forbid array comparisons in GLSL 1.10

28009cd75c Begin handling array declarations 
This causes the following tests to pass:

    glslparsertest/shaders/array4.frag
    glslparsertest/shaders/array5.frag

This causes the following tests to fail.  These shaders were
previously failing to compile, but they were all failing for the wrong
reasons.

548a1b5ab7 Implement array type handling 
Since all glsl_type objects are flyweights, support is added to track all
known array types.  This accounts for most of the changes.

bfb09c2a94 Use call-by-reference for apply_implicit_conversion 
I'm not sure if this is a win or not.  It makes the code in
apply_implicit_conversion more clear, but it obscures the fact that it
may change the pointers.

This causes the following tests to pass:

    glslparsertest/shaders/CorrectVersion.V110.frag
    shaders/glsl-vs-sqrt-zero.frag
    shaders/glsl-vs-sqrt-zero.vert

This causes the following tests to fail.  These shaders were

3c6fea3048 Implement ir_if (for if-statments) and conversion from AST 
The following tests now pass:

    glslparsertest/shaders/if1.frag
    glslparsertest/shaders/if2.frag

The following tests that used to pass now fail.  It appears that most
of these fail because ast_nequal and ast_equal are not converted to HIR.

Matches constructor setup, but I'm not really sure why we make the
variable twice.

01665262e5 Implement exp2() and log2(), and make ir_unop_exp and ir_unop_log be base e. 
Making the base e functions IR operations is not a clear win.  i965
doesn't support it, it doesn't look like r600 supports it, but r500
does. It should be easily supportable as a lowering pass, though.

44d68fd06f Add sqrt() builtin as an IR operation. 
Following a discussion in #dri-devel, I think this makes more sense
than implementing it as RSQ RCP CMP as Mesa did.  The i965 has a
hardware sqrt that should work, and AMD is suppposed to be able to
implement it as RSQ RCP with an alternate floating point mode so that
the 0.0 case is handled like we want.
