Use a heap-memory traversal to free compiler resources.
The stack-memory traversal is prone to stack overflow. See the
WebGL conformance test long-expressions-should-not-crash.

Add an option to unfold short circuiting in AST.
We replace "a || b" with "a ? true : b",
"a && b" with "a ? b : false".
This is to work around short circuiting bug in Mac drivers.

Fix issues with the conditional discard workarounds to do with assignments.
The old modifiesState method really checked if an operator was an assignment,
so restored that behaviour and use the new side effects detection only for
the new code.

Disable optimizations for shaders with conditional discard in D3D9, and
only use expanded short-circuiting conditionals for expressions with
potential side-effects.
Conservatively assume aggreate and selection operators have side effects for now.

Moved the compiler source files into directories based on their project and added a compiler.gypi to generate the compiler projects.
