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).

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

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.

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:

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.

Newb GL mistake: matrices in GL are column-major. This means that
