Improve branch operations (#1442)
* Add Compare instruction

* Add BranchIf instruction

* Use test when BranchIf & Compare against 0

* Propagate Compare into BranchIfTrue/False use

- Propagate Compare operations into their BranchIfTrue/False use and
  turn these into a BranchIf.

- Clean up Comparison enum.

* Replace BranchIfTrue/False with BranchIf

* Use BranchIf in EmitPtPointerLoad

- Using BranchIf early instead of BranchIfTrue/False improves LCQ and
  reduces the amount of work needed by the Optimizer.

  EmitPtPointerLoader was a/the big producer of BranchIfTrue/False.

- Fix asserts firing when assembling BitwiseAnd because of type
  mismatch in EmitStoreExclusive. This is harmless and should not
  cause any diffs.

* Increment PPTC interval version

* Improve IRDumper for BranchIf & Compare

* Use BranchIf in EmitNativeCall

* Clean up

* Do not emit test when immediately preceded by and
