140575ee71 C++: Use StackVariable where SSA/def-use are used 
These changes should not affect semantics since these uses of
`LocalScopeVariable` were already constrained to stack variables by
their use of SSA or def-use.

29f66ff095 C++: Use StackVariable, remove not v.isStatic() 
In these files it was possible to remove calls to `isStatic` by
switching from `LocalScopeVariable` to `StackVariable`. This changes
semantics, hopefully for the better, to treat `thread_local` locals the
same as `static` locals.

c1ed908834 C++: Use StackVariableReachability 
This library is a drop-in replacement for
`LocalScopeVariableReachability`, so no changes are expected.

64a87a863c C++: Remove uses of getQualifiedName 
This removes all uses of `Declaration.getQualifiedName` that I think can
be removed without changing any behaviour. The following uses in the
LGTM default suite remain:

* `cpp/ql/src/Security/CWE/CWE-121/UnterminatedVarargsCall.ql` (in `select`).
* `cpp/ql/src/semmle/code/cpp/dataflow/internal/DataFlowDispatch.qll` (needs template args).
* `cpp/ql/src/semmle/code/cpp/security/FunctionWithWrappers.qll` (used for alert messages).

9d15e67f3c C++: Use variableAccessedAsValue in LargeParameter 
Using `variableAccessedAsValue` fixes a FP because we can now
distinguish modifications to the parameter from modifications to data
_reachable from_ the parameter.
