e46a454305 ir: Give ir_instruction a print visitor helper. 
This avoids spamming each file with includes of ir_print_visitor.h
because someone was doing debugging at some point, and is less typing
when doing debugging.

f3a002b503 Refactor ir_dereference support for ir_hierarchical_visitor 
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.

6255a1f4c6 ir_dead_code_local: Remove redundant assignments within basic blocks. 
This cleans up a bunch of junk code in some of the GLSL parser tests,
and could potentially help real-world too (particularly after copy
propagation has happened).
