(I think it's reasonably clear that we want to have a canonical form for 
constructs like this; if anyone thinks that a select is not the best 
canonical form, please tell me.)

 - Like -noremove, except the build directory is still purged prior to building
   but isn't removed at the end of the test run (so the build products can be
   examined if need be).

and related functions out of LoopBase and into Loop, since they
are specific to BasicBlock-based loops. This also allows the code
to be moved out-of-line.

using the Curiously Recurring Template Pattern with LoopBase.

This will help further refactoring, and future functionality for
Loop. Also, Headers can now foward-declare Loop, instead of pulling
in LoopInfo.h or doing tricks.

the changes are allowed by not calling this function for bitcasts.  
The Instruction::AShr case is dead because 
SimplifyDemandedInstructionBits handles that case.

Add infrastructure to allow post instruction printing action triggers.
We'll eventually use this to print comments in asm files and do other
fun things.

This adds interfaces to the AsmPrinter and changes TableGen to invoke
the postInstructionAction when appropriate.  It also add parameters to
TargetAsmInfo to control comment layout.
