Summary:
This change moves tests for checkers and infrastructure into separate
directories, making it easier to find infrastructure tests. Tests for
checkers are already easy to find because they are named after the
checker. Tests for infrastructure were difficult to find because they
were outnumbered by tests for checkers. Now they are in a separate
directory.

Summary:
I inspected every test and did one of the following:
- changed the test to run in all language modes,
- added a comment explaining why the test is only applicable in a
certain mode,
- limited the test to language modes where it passes and added a FIXME
to fix the checker or the test.

Test failed as D52120 made ExprMutationAnalyzer smarter, fixed by:
- Add move-ctor for `Mutable` to make it actually movable.
- Properly implement `remove_reference`.
The failed test case is:
void negativeVarIsMoved() {
for (auto M : View<Iterator<Mutable>>()) {
auto Moved = std::move(M);
}
}
Before D52120, `std::move(M)` itself is considered as a mutation to `M`,
while after D52120 it's only considered as a cast to rvalue, the
move-assignment is what causes the actual mutation. The test case didn't
mock things properly so the intended move-assignement was actually a
copy-assignment.

performance-for-range-copy check.
Summary:
The upstream change r336737 make the check too smart to fix the case
where loop variable could be used as `const auto&`.
But for the case below, changing to `const auto _` will introduce
an unused complier warning.
```
for (auto _ : state) {
// no references for _.
}
```
This patch omit this case, and it is safe to do it as the case is very rare.

Summary:
This gives better coverage to the check as ExprMutationAnalyzer is more
accurate comparing to isOnlyUsedAsConst.
Majority of wins come from const usage of member field, e.g.:
for (auto widget : container) { // copy of loop variable
if (widget.type == BUTTON) { // const usage only recognized by ExprMutationAnalyzer
// ...
}
}
