ir_dead_code_local: Remove redundant assignments within basic blocks.
...
This cleans up a bunch of junk code in some of the GLSL parser tests,
and could potentially help real-world too (particularly after copy
propagation has happened).

ir_copy_propagation: New pass to rewrite dereferences to avoid copies.
...
This is pretty basic. Right now it only handles pure assignments --
same type on each side, no swizzling, and only within basic blocks.

ir_function_inlining: Implement inlining in many more cases.
...
We still don't inline for control flow in the inlined function, and we
don't have any limits on what we will inline.

Replace builtin_types.h generation with the generated output.
...
The script to generate it was longer and more obfuscated than the output.

Remove dead code assignments and variable declarations.
...
This pass only works on assignments where the variable is never
referenced. There is no code flow analysis, so it can't do a better
job of avoiding redundant assignments.
For now, the optimizer only does do_dead_code_unlinked(), so it won't
trim the builtin variable list or initializers outside of the scope of
functions. This is because we don't have the visibility into other
functions that might get linked in in order to eliminate work on
global variables.

Add an ir_if simplification pass.
...
This is relatively simple at the moment, recognizing only constant
values, and not (for example) values that are restricted to a range
that make the branching constant. However, it does remove 59 lines
from the printout of CorrectParse2.vert.

Include other generated sources in BUILT_SOURCES.
...
Otherwise, having cleaned glsl_parser.h, we'd never regenerate it because
glsl_parser.cpp was already right where it needed to be.

Initial pass at resolving function calls
...
The code is still really rough and *REALLY* incomplete. This at least
passes the first few trivially simple test cases.

IR visitor: Add initial version of ir_visitor classes

The ir_visitor class is the abstract base class for all visitors.
ir_print_visitor contains the beginnings of a concrete visitor class
that will print out an IR sequence in a Lisp / Scheme-like syntax.
