* assembler/LinkBuffer.h:
(JSC::LinkBuffer::offsetOf):
    - We use this to return the offsets into the code of the entry points.
* dfg/DFGJITCompiler.cpp:
(JSC::DFG::JITCompiler::compileEntry):
(JSC::DFG::JITCompiler::compileBody):
(JSC::DFG::JITCompiler::compile):
(JSC::DFG::JITCompiler::compileFunction):
    - Move the construction of the speculative JIT outside of
      compileBody, such that it is still available to link the
      OSR entry points at the point we are linking.
* dfg/DFGJITCompiler.h:
(JSC::DFG::JITCompiler::noticeOSREntry):
    - Pass the label of the block & linkbuffer into noticeOSREntry.
* dfg/DFGSpeculativeJIT.cpp:
(JSC::DFG::SpeculativeJIT::compile):
(JSC::DFG::SpeculativeJIT::linkOSREntries):
    - Moved call to noticeOSREntry until we we linking.
* dfg/DFGSpeculativeJIT.h:
* jit/JIT.cpp:
(JSC::JIT::privateCompileMainPass):
