ef4a89c479 [Exclusivity] Enforce exclusive access for class offsets in KeyPaths
Add dynamic enforcement of exclusive access when a KeyPath directly accesses a final
stored property on an instance of a class. For read-only projections, this begins and ends
the access immediately. For mutable projections, this uses the ClassHolder to perform
a long-term access that lasts as long as the lifetime of the ClassHolder.

b67d5f0cf7 test: convert rm -rf && mkdir -p into %empty-directory
This converts the instances of the pattern for which we have a proper
substitution in lit.  This will make it easier to replace it
appropriately with Windows equivalents.
