Alexander Kornienko 6ae0a630b8 [clang-tidy] misc-sizeof-container: remove fix-it hints
This turned out to be a rather noisy check, so automated fixes will only do
harm. Remove them completely.

Alexander Kornienko 541de378ce [clang-tidy] misc-sizeof-container: whitelist std::bitset<>.
It's fine to use sizeof on std::bitset<>, since it doesn't have any external
storage, everything's inside.

Alexander Kornienko 7532d3e93d [clang-tidy] Add misc-sizeof-container check to find sizeof() uses on stl
containers.

Summary:
sizeof(some_std_string) is likely to be an error. This check finds this
pattern and suggests using .size() instead.

Alexander Kornienko f8ed0a8d35 [clang-tidy] Update docs for clang-tidy checks. NFC
Changes mostly address formatting and unification of the style. Use
MarkDown style for inline code snippets and lists. Added some text
for a few checks.

The idea is to move most of the documentation out to separate rST files and have
implementation files refer to the corresponding documentation files.

Ehsan Akhgari c62c639610 Insert override at the same line as the end of the function declaration
Summary:
The existing check converts the code pattern below:

  void f()
  {
  }

to:

  void f()
  override {
  }

which is fairly sub-optimal.  This patch fixes this by inserting the
override keyword on the same line as the function declaration if
possible, so that we instead get:

  void f() override
  {
  }

We do this by looking for the last token before the start of the body
and inserting the override keyword at the end of its location.  Note
that we handle const, volatile and ref-qualifiers correctly.

Test Plan: Includes an automated test.

Daniel Jasper 9fe55a32b7 misc-unused-parameters: Don't warn on ParmVarDecls in the return type.
As there don't seem to be a good way of formulating a matcher that
finds all pairs of functions and their ParmVarDecls, just match on
functionDecls and iterate over their parameters. This should also be
more efficient as some checks are only performed once per function.
