History
Nate Begeman 486ebfd704 Fix Shootout-C++/wc, which was broken by my recent changes to emit fewer 
reg-reg copies.  The necessary conditions for this bug are a GEP that is
used outside the basic block in which it is defined, whose components
other than the pointer are all constant zero, and where the use is
selected before the definition (backwards branch to successsor block).

TODO:
* poor switch statement codegen
* load/store to alloca'd array or struct.
* implement not-R0 register GPR class
* implement scheduling info
* implement do-loop pass
* implement do-loop -> bdnz transform
* implement powerpc-64 for darwin
* implement powerpc-64 for aix
* use stfiwx in float->int
* should hint to the branch select pass that it doesn't need to print the
  second unconditional branch, so we don't end up with things like:
	b .LBBl42__2E_expand_function_8_674	; loopentry.24
	b .LBBl42__2E_expand_function_8_42	; NewDefault
	b .LBBl42__2E_expand_function_8_42	; NewDefault

Currently failing tests that should pass:
* MultiSource
