Alexander Kornienko 761c25bc15 [clang-tidy] Test username substitution in TODO() check.
Summary:
This patch depends on D5501.
Check user name substitution more specifically by specifying it via the new
-config= option.
This also lets clang-tidy tests specify clang-tidy options before the '--'
when using check_clang_tidy_fix.sh.

Summary:
This uses a bit hacky way to set the defaults for the spaces before
comments, but it's also one of the simplest ways. Fixed a bug with how the
SpacesBeforeComments option was used.

Benjamin Kramer 6e195426e7 [clang-tidy] Add a checker for long functions.
As this is very dependent on the code base it has some ways of configuration.
It's possible to pick between 3 modes of operation:

- Line counting: number of lines including whitespace and comments
- Statement counting: number of statements within compoundStmts.
- Branch counter

In addition a threshold can be picked, warnings are only emitted when it is met.
The thresholds can be configured via a .clang-tidy file.

Benjamin Kramer 1188792480 [clang-tidy] Add a checker for code that looks like a delegate constructors but doesn't delegate.
Summary:
class Foo {
  Foo() {
    Foo(42); // oops
  }
  Foo(int);
};

This is valid code but it does nothing and we can't emit a warning in clang
because there might be side effects. The checker emits a warning for this
pattern and also for base class initializers written in this style.

There is some overlap with the unused-rtti checker but they follow different
goals and fire in different places most of the time.

Benjamin Kramer da3658e2b7 Reapply r213647 with a fix.
ASTMatchers currently have problems mixing bound TypeLoc nodes with Decl/Stmt
nodes. That should be fixed soon but for this checker there we only need the
TypeLoc to generate a fixit so postpone the potentially heavyweight AST walking
until after we know that we're going to emit a warning.

This is covered by existing test cases.

Original message:
[clang-tidy] Add a check for RAII temporaries.

This tries to find code similar that immediately destroys
an object that looks like it's trying to follow RAII.
  {
    scoped_lock(&global_mutex);
    critical_section();
  }

This checker will have false positives if someone uses this pattern
to legitimately invoke a destructor immediately (or the statement is
at the end of a scope anyway). To reduce the number we ignore this
pattern in macros (this is heavily used by gtest) and ignore objects
with no user-defined destructor.
