6b51ac6728 Canonicalize boolean +/- a constant to a select. 
(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.)

2692bf38f5 NewNightlyTest.pl - Add -noremoveatend option. 
- 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).

9a7df22e10 Move isLCSSAForm, isLoopInvariant, getCanonicalInductionVariable, 
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.

f6caa6f1e3 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.

b2a8c4ffc9 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.

a9953c0a28 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.

1a780ad8db Move the memoization check for SCEVSignExtendExpr and 
SCEVZeroExtendExpr ahead of the most expensive analysis. This
speeds up analysis and helps avoid pathologically bad behavior
on the testcase in PR4534.

bitcasts will always be eliminated anyway.

bf3719359b Convert SCEV from FoldingSetNode to FastFoldingSetNode. This eliminates 
a bunch of redundent code in Profile methods, and prepares for upcoming
changes to do improved memoization.

814f6a648f 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.

always adds a newline, so this fixes Value::dump printing an
extra blank line.

b4bd955891 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.
