This will improve the performance of ENABLE(ASSEMBLER_WX_EXCLUSIVE) builds.
Created attachment 33406 [details] The Patch.
It looks like this patch might create conflicts with the merge I'm working on. The PtrAndFlags, StructureStubInfo and CodeBlock changes probably won't conflict, and removing virtualCallPreLinkBegin probably won't conflict too much (modulo a file move), but I'm worried that the JITCall and JITStubs changes risk making diff very confused, since I've made a lot of changes in the same areas. Do you think you can hold off landing until after Friday? I gave the patch a brief review, and it looks good to me.
