*	glsl2: Use as_constant some places instead of constant_expression_value	Ian Romanick	2010-09-03	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \|	The places where constant_expression_value are still used in loop analysis are places where a new expression tree is created and constant folding won't have happened. This is used, for example, when we try to determine the maximal loop iteration count. Based on review comments by Eric. "...rely on constant folding to have done its job, instead of going all through the subtree again when it wasn't a constant."
*	glsl2: Track the number of ir_loop_jump instructions that are in a loop	Ian Romanick	2010-09-03	1	-0/+17

*	glsl2: Add module to analyze variables used in loops	Ian Romanick	2010-09-03	1	-0/+479
	This is the first step eventually leading to loop unrolling.
