Michael Gottesman 3e64d03a52 [exclusivity] Split out of Exclusivity.cpp FunctionReplacement and the Global TLSContext.
Some notes:

1. Even though I refactored out AccessSet/Access from Exclusivity.cpp ->
ExclusivityPrivate.h, I left the actual implementations of insert/remove in
Exclusivity.cpp to allow for the most aggressive optimization for use in
Exclusivity.cpp without exposing a bunch of internal details to other parts of
the runtime. Smaller routines like getHead() and manipulating the linked list
directly I left as methods that can be used by other parts of the runtime. I am
going to use these methods to enable backwards deployment of exclusivity support
for concurrency.

2. I moved function replacements out of the Exclusivity header/cpp files since
it has nothing to do with Exclusivity beyond taking advantage of the TLS context
that we are already using.
