Offlineasm cloop backend compiles op+branch incorrectly.
https://bugs.webkit.org/show_bug.cgi?id=113146.

Reviewed by Geoffrey Garen.

* dfg/DFGRepatch.h:
(JSC::DFG::dfgResetGetByID):
(JSC::DFG::dfgResetPutByID):
- These functions never return when the DFG is dsiabled, not just when
  asserts are enabled. Changing the attribute from NO_RETURN_DUE_TO_ASSERT
  to NO_RETURN.
* llint/LLIntOfflineAsmConfig.h:
- Added some #defines needed to get the cloop building again.
* offlineasm/cloop.rb:
- Fix cloopEmitOpAndBranchIfOverflow() and cloopEmitOpAndBranch() to
  emit code that unconditionally executes the specified operation before
  doing the conditional branch.
