	e53c98ba	2014-02-03T11:57:13		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'.

	3c9eeb97	2013-11-04T11:09:26		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.
