[clang][dataflow] Generalise match switch utility to other AST types and add a `CFGMatchSwitch` which currently handles `CFGStmt` and `CFGInitializer`.
`MatchSwitch` currently takes in matchers and functions for the `Stmt` class.
This patch generalises the match switch utility (renamed to `ASTMatchSwitch`) to work for different AST node types by introducing a template argument which is the base type for the AST nodes that the match switch will handle.
A `CFGMatchSwitch` is introduced as a wrapper around multiple `ASTMatchSwitch`s for different base types. It works by unwrapping `CFGElement`s into their contained AST nodes and passing the nodes to the relevant `ASTMatchSwitch`. The `CFGMatchSwitch` currently only handles `CFGStmt` and `CFGInitializer`.

[clang][dataflow] Replace TEST_F with TEST where possible
Many of our tests are currently written using `TEST_F` where the test fixture class doesn't have any `SetUp` or `TearDown` methods, and just one helper method. In those cases, this patch deletes the class and pulls its method out into a standalone function, using `TEST` instead of `TEST_F`.
There are still a few test files leftover in `clang/unittests/Analysis/FlowSensitive/` that use `TEST_F`:
- `DataflowAnalysisContextTest.cpp` because the class contains a `Context` field which is used
- `DataflowEnvironmentTest.cpp` because the class contains an `Environment` field which is used
- `SolverTest.cpp` because the class contains a `Vals` field which is used
- `TypeErasedDataflowAnalysisTest.cpp` because there are several different classes which all share the same method name

[clang][dataflow] Allow MatchSwitch to return a value
This patch adds another `typename` parameter to `MatchSwitch` class: `Result` (defaults to `void`), corresponding to the return type of the function. This necessitates a couple minor changes to the `MatchSwitchBuilder` class, and is tested via a new `ReturnNonVoid` test in `clang/unittests/Analysis/FlowSensitive/MatchSwitchTest.cpp`.
