Since overrides can be used to size workgroup arrays and also as
initializers to module-scope variables, we cannot just consider
overrides that are directly referenced in the shader functions.
This change makes the Resolver track references to overrides whilst
resolving array types and module-scope variable declarations, so that
they are included in the set of overrides reported by the Inspector in
these scenarios.

Track reads and writes to pointer parameters for each function in the
Resolver, as well as accesses to module-scope variables. At function
call sites, check the root identifiers of each pointer argument to
determine if problematic aliasing occurs.
The MSL backend passes pointers to sub-objects to functions when
handling workgroup storage variables, which triggers the alias
analysis. Add a validation override for this scenario.

This is the same as was done for const eval builtin tests, allowing the
error cases to be defined in the same place as we define the positive
cases.
Also got rid fo the 'overflow' flag, which was used to skip abstract
cases in the unit test. Instead, I modified the tests to only add
overflow cases if not abstract.
This change will make it easier to update tests when we make Inf/NaN
failures for concrete float operations.
