7dd6adbe2e Refactor ir_expression::get_num_operands. 
A new static version takes an ir_expression_operation enum, and the
original non-static version now uses it.  This will make it easier to
read operations (where the ir_expression doesn't yet exist).

9fa99f3b6c Refactor IR function representation. 
Now, ir_function is emitted as part of the IR instructions, rather than
simply existing in the symbol table.  Individual ir_function_signatures
are not emitted themselves, but only as part of ir_function.

894ea972a4 Put function bodies under function signatures, instead of flat in the parent. 
This will let us know the length of function bodies for the purpose of
inlining (among other uses).

9d975377ca Track whether whole-arrays are assignable 
In GLSL 1.10 this was not allowed, but in GLSL 1.20 and later it is.

This causes the following tests to pass:

    glslparsertest/glsl2/array-09.vert
    glslparsertest/glsl2/array-13.vert

2d946634eb Whole structures are assignable 
Whole arrays are assignable in GLSL 1.20 and later, but it's not clear
how to handle that within the IR because the IR is supposed to be
shading language version agnostic.

Fixes glsl-vs-arrays.vert and glsl-vs-mov-after-deref.vert.
Regresses parser3.frag which was failing for the wrong reason.

b8a21cc6df Track max accessed array element, reject additional out-of-bounds accesses 
For unsized arrays, we can't flag out-of-bounds accesses until the
array is redeclared with a size.  Track the maximum accessed element
and generate an error if the declaration specifies a size that would
cause that access to be out-of-bounds.

This causes the following tests to pass:

    glslparsertest/shaders/array10.frag

affc1413ac Move swizzles out of ir_dereference and into their own class. 
Also turn generate_swizzle into a static "create" method of the new
class; we'll want to use it for the IR reader as well.

These should work well even in a non-flat IR hierarchy.

1b4f04124a Fix matrix dimensioning 
Newb GL mistake: matrices in GL are column-major.  This means that
vector_elements is the number of rows.  Making these changes causes
matrix-08.glsl to pass.
