6bdf186d1e C tests: generalize arguments tests 
With the coming `codeql test` support, the `predefined_macros` file will not
necessarily be located under a `tools` directory. Change the test to hide more
of its actual path, so it will work in both cases.

f3b4140948 C++/C#: Consistent handling of "may" vs. "must" memory accesses 
In the IR, some memory accesses are "must" accesses (the entire memory location is always read or written), and some are "may" accesses (some, all, or none of the bits in the location are written). We previously had to special case specific "may" accesses in a few places. This change regularizes our handling of "may" accesses.

The `MemoryAccessKind` enumeration now describes only the extent of the access (the set of locations potentially accessed), but does not distinguish "must" from "may". The new predicates `Operand.hasMayMemoryAccess()` and `Instruction.hasResultMayMemoryAccess()` hold when the access is a "may" access.

Unaliased SSA now correctly ignores variables that are ever accessed via a "may" access.

Aliased SSA now distinguishes `MemoryLocation`s for "may" and "must" accesses. I've refactored `getOverlap()` into the core `getExtentOverlap()`, which considers only the extent, but not the "may" vs. "must", and `getOverlap()`, which tweaks the result of `getExtentOverlap()` based on "may" vs. "must" and read-only locations.

When determining the overlap between a `Phi` operand and its definition, we now use the result of the defining `Chi` instruction, if one exists. This gives exact definitions for `Phi` operands for virtual variables.

8d79634f8c C++: Factor out isFromMacroDefinition predicate 
This trick for excluding elements from macro bodies but not macro
arguments looks promising and should probably be used much more. With
this commit, it's now easy to use from any query.

Performance is still good because the new predicate gets appropriately
magiced.
