With lazy feedback allocation, for functions that get OSRed we may not have feedback for the initial part of the functions since feedback vectors might be allocated after the function started executing. Hence we would not be able to optimize the function on the next call. This means we may have to OSR twice before we actually optimize function. This cl introduces OSR cache, so we could reuse the optimized code. One side effect of this cl is that the OSRed code won't be function context specialized anymore.

This CL removes the StoreBuffer and inserts slots into the RememberedSet directly from within the RecordWrite builtin. Only calls into C code when either the SlotSet-array or the bucket is not allocated. This avoids filling the store buffer up with duplicates or due to a write-heavy workload and then blocking the main thread on store buffer processing.

Bytecodes used by the regular expression interpreter often occur in specific sequences. The number of dispatches in the interpreter can be reduced if those sequences are combined into a single bytecode. This CL adds a peephole optimization pass for regexp bytecodes. This pass checks the generated bytecode for pre-defined sequences that can be merged into a single bytecode. With the currently implemented bytecode sequences a speedup of 1.12x on regex-dna and octane-regexp is achieved.

It looks like codegen on ia32 may sometimes miss a byte during emit_arith. Our working theory is that this happens because `length` in emit_operand, for whatever reason, is 0 and we thus do not advance `pc_` correctly. The tentative fix is to use EMIT to increment the pc_ on each single write instead of relying on `length`.

A lot of the instructions in RO_OP_LIST do not require temp registers in the codegen, but a temp register is emitted. We split RO_OP_LIST into two lists, one which requires temp registers RO_OP_LIST_ONE_TEMP, and RO_OP_LIST is now for instructions that do not use temp registers. There are a couple more instructions currently in RO_OP_LIST, but use scratch registers in the codegen, those can be cleaned up to use temp registers and then moved into RO_OP_LIST_ONE_TEMP.
