Julian Seward 18b7ed0c53 Merge patch from JeremyF:
39-lock-prefix

Add a new UInstr LOCK to represent a "lock" prefix in the instruction
stream. This has the same semantics as NOP, but allows a skin to tell
whether a group of UInstrs associated with an x86 instruction are
meant to be locked.

HELGRIND: uses the LOCK UInstr to automatically take and release a
special __BUS_HARDWARE_LOCK__ around locked instructions. This only
works properly if all instructions touching a given address are locked
(even reads).
