c8d76d5afb Make Loop and MachineLoop be subclasses of LoopBase, rather than typedefs, 
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.

92aa0bb4ca refactor operand printing to remove hte last of the "mem" modifier hack. The 
only remaining modifier is "subreg".

65445c5b14 Misc simplifications to InstCombiner::commonIntCastTransforms. Most of 
the changes are allowed by not calling this function for bitcasts.  
The Instruction::AShr case is dead because 
SimplifyDemandedInstructionBits handles that case.

85b05a2e60 Reapply 75252, with a fix to avoid the infinite recursion case. The 
check for avoiding re-analyzing a widening cast needed to happen
earlier, as getSCEV itself may result in a isLoopGuardedByCond query.

014700c1a8 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.

6fbc1969e9 Move the re-sort of invalidated NonLocalPointerDeps cache earlier 
so that all code paths get it.  PR4256 was about a case where the
phi translation loop would find all preds in the Visited cache, so
it could get by without re-sorting the NonLocalPointerDeps cache.
Fix this by resorting it earlier, there is no reason not to do this.

This patch inspired by Jakub Staszak's patch.

0a5372ed3e Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp.

implemented in codegen, have no frontend to generate them, and are 
better implemented with pattern matching (like the ppc backend does
to generate rlwimi/rlwinm etc).
