1) unique globals with the existing "Count" local in Mangler, not with
atomic nonsense. Using atomics will give us nondeterminstic output
from the compiler when using multiple threads, which is bad.
2) Do not mangle an unknown global name with a type suffix. We don't
need this anymore now that llvm ir doesn't have type planes.

(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.

check for avoiding re-analyzing a widening cast needed to happen
earlier, as getSCEV itself may result in a isLoopGuardedByCond query.

SCEVZeroExtendExpr ahead of the most expensive analysis. This
speeds up analysis and helps avoid pathologically bad behavior
on the testcase in PR4534.

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.

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.
