2010-05-26	Refactor ir_dereference support for ir_hierarchical_visitor	Ian Romanick
	Move the accept method for hierarchical visitors from ir_dereference to the derived classes. This was mostly straight-forward, but I suspect that ir_dead_code_local may be broken now.
2010-05-18	Use ir_rvalue::variable_referenced instead of open coding it	Ian Romanick

2010-05-17	Reimplement ir_dead_code_visitor using ir_hierarchical_vistor	Ian Romanick
	The output of all test cases was verified to be the same using diff.
2010-05-17	Replace find_dead_code with visit_exec_list	Ian Romanick
	find_dead_code appears to be an open-coded version of visit_exec_list that was implemented first.
2010-04-29	ir_dead_code: Fix segfault on handling a return statement with no value.	Eric Anholt

2010-04-21	Fix ir_dead_code for function refactoring.	Kenneth Graunke

2010-04-19	Remove dead code assignments and variable declarations.	Eric Anholt
	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.
