Flag ints as type INT in the incoming context if its merely a double holding an int that was too large to fit into jsval directly. Along the side exits make sure we can properly box oversized ints (by casting them to doubles). The fetch_int/store_int paths still need fixing to ensure that values are merely passed through (prim_copy) instead of explicit casting or calling to ValueToECMAInt32 etc.

Save the VM registers into markRegs at opcode entry and restore that state when ending or aborting recording. The same info is pushed into sideexit and used by guards. With this change we can eliminate the hack in MONITOR_BRANCH that had to adjust the stack pointer depending on the opcode type, and it also allows us to trace through the recently added boolean guard opcode fusing. This improves trace code quality, since only the pre-conditional check state is saved. The guard restores into that state, so the trace code doesn't have to emit the value of the conditional evaluation onto the stack, saving a handful ops.
