Summary:
This patch uses CHECK-NOTES for the tests.
Its part of an effort to test *ALL* generated diagnostics in clang-tidy,
as emitted notes were previously ignored.

Summary:
We can use cl::ResetCommandLineParser() to support different types of
command-lines, as long as we're careful about option lifetimes.
(I tried using subcommands, but the error messages were bad)
I found a mostly-reasonable pattern to isolate the fiddly parts.
Added -scope and -limit flags to the `find` command to demonstrate.
(Note that scope support seems to be broken in dex?)
Fixed symbol lookup to parse symbol IDs.
Caveats:
- with command help (e.g. `find -help`), you also get some spam
about required arguments. This is a bug in llvm::cl, which prints
these to errs() rather than the designated stream.

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.

Summary:
PR37913 documents wrong behaviour for a templated exception factory function.
The check does misidentify dependent types as not derived from std::exception.
The fix to this problem is to ignore dependent types, the analysis works correctly
on the instantiated function.

Summary:
Hello, i would like to suggest a fix for one of the checks in clang-tidy.The bug was reported in https://bugs.llvm.org/show_bug.cgi?id=32575 where you can find more information.
For example:
```
template <typename T0>
struct S {
template <typename T>
void g() const {
int a;
(void)a;
}
};
void f() {
S<int>().g<int>();
}
```
this piece of code should not trigger any warning by the check modernize-redundant-void-arg but when we execute the following command
```
clang_tidy -checks=-*,modernize-redundant-void-arg test.cpp -- -std=c++11
```
we obtain the following warning:
/Users/eco419/Desktop/clang-tidy.project/void-redundand_2/test.cpp:6:6: warning: redundant void argument list in function declaration [modernize-redundant-void-arg]
(void)a;

Given that the indexer binary is put directly into ./bin directory

reader than 'global-'.
The new name is also shorter and easier to type.

Summary:
The check_clang_tidy.py script would allow mixing of `CHECK-NOTES` and `CHECK-MESSAGES` but running `FileCheck` for that would implicitly fail, because `CHECK-NOTES` bails out if there is a warning.
That means a clang-tidy test can not mix these constructs to check warnings with `CHECK-MESSAGES` and notes with `CHECK-NOTES`. The script gives now a clear error if that happens.

Summary:
Currently, there is two configured prefixes: `CHECK-FIXES` and `CHECK-MESSAGES`
`CHECK-MESSAGES` checks that there are no test output lines with `warning:|error:`, which are not explicitly handled in lit tests.
However there does not seem to be a nice way to enforce for all the `note:` to be checked.
This was useful for me when developing D36836.

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.
