ALL THE CODE IN THIS FILE RUNS ON THE SIMULATED CPU.
These functions are not called directly - they're the targets of code
redirection or load notifications (see pub_core_redir.h for info).
They're named weirdly so that the intercept code can find them when the
shared object is initially loaded.
Note that this filename has the "drd_" prefix because it can appear
in stack traces, and the "drd_" makes it a little clearer that it
originates from Valgrind.
