Clean up TIntermTraverser usage
Remove default parameters from TIntermTraverser.
Also clean up a few dead function declarations in traversers.

Set mUsesDiscardRewriting more conservatively
This fixes a regression from recent refactoring of unfolding short-circuiting
operators. mUsesDiscardRewriting used to be set based on detecting patterns
that the AST traverser now overwrites before the code reaches OutputHLSL. With
this patch mUsesDiscardRewriting is set more conservatively, which ensures that
using discard works correctly also in case the input shader contains the same
kind of pattern as the short-circuiting operator unfolding creates.

Rename compiler intermediate source files.
This prevents confusion between "TIntermediate" and "TIntermNode".

Add work-around for D3D9 shader compiler bug.
With certain selection statements with a vertex input in the
condition and side-effects in the else-block, we'd run in to
a D3D9 compiler bug which would cause incorrect results.
We can work around this bug in D3D9 by selectively rewriting
these statements to use an 'else if' clause instead of 'else'.

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.
