Move DFG inline caching logic into jit/
https://bugs.webkit.org/show_bug.cgi?id=121749
Rubber stamped by Sam Weinig.
We want to get rid of the baseline JIT's inline caching machinery and have it use the
DFG's instead. But before we do that we need to move the DFG's inline caching machine
out from behind its ENABLE(DFG_JIT) guards and make it available to the whole system.
This patch does that:
- dfg/DFGRepatch becomes jit/Repatch.
- The thunks used by the DFG IC go into jit/ThunkGenerators, instead of dfg/DFGThunks.
- The operations used by the DFG IC go into jit/JITOperations, instead of
dfg/DFGOperations.
- The old JIT's thunk generators for calls are renamed to reduce confusion. Previously
it was easy to know which generators belong to which JIT because the old JIT used
JSC::virtualCallBlah and the DFG used JSC::DFG::virtualCallBlah, but that's not the
case anymore. Note that the old JIT's thunk generators will die in a future patch.
No functional changes beyond those moves.
