Tess Strickland 0f8861e3ba [vm] Standardize hashing instance methods in C++.
In the codebase, we have several different interfaces for instance
methods that return a hash:

- uword Hash() const;
- intptr_t Hash() const;
- uint32_t Hash() const;
- intptr_t Hashcode() const;

This CL standardizes on `uword Hash() const` and adjusts any related
functions to match.

TEST=Existing test suites, as this is an internal refactoring.
