Haojian Wu 4b956cb70d [clang-tidy] Don't generate fixes for initializer_list constructor in make_unique check. 
Summary:
The current fix will break the compilation -- because braced list is not
deducible in std::make_unique (with the use of forwarding) without
specifying the type explicitly.

We could support it in the future.

Richard Smith 02c3baaad2 Fix ODR violations due to abuse of LLVM_YAML_IS_(FLOW_)?SEQUENCE_VECTOR 
This is a short-term fix for PR33650 aimed to get the modules build bots green again.

Remove all the places where we use the LLVM_YAML_IS_(FLOW_)?SEQUENCE_VECTOR
macros to try to locally specialize a global template for a global type. That's
not how C++ works.

Instead, we now centrally define how to format vectors of fundamental types and
of string (std::string and StringRef). We use flow formatting for the former
cases, since that's the obvious right thing to do; in the latter case, it's
less clear what the right choice is, but flow formatting is really bad for some
cases (due to very long strings), so we pick block formatting. (Many of the
cases that were using flow formatting for strings are improved by this change.)

Other than the flow -> block formatting change for some vectors of strings,
this should result in no functionality change.

Haojian Wu 25e54c93bb [clang-tidy] Fix a false positive in modernize-use-nullptr. 
Summary:
The FP happens when a casting nullptr expression is used within a NULL-default-arguemnt cxx constructor.

Before the fix, the check will give a warning on nullptr when running
with the test case, which should not happen:

```
G(g(static_cast<char*>(nullptr)));
    ^~~~~~~~~~~
    nullptr
```

Roman Lebedev eb6d821cda [clang-tidy] readability-function-size: fix nesting level calculation 
Summary:
A followup for D32942.

Malcolm Parsons has provided a valid testcase that the initial version of the check complained about nested `if`'s.
As it turns out, the culprit is the **partially** un-intentional `switch` fallthrough.
So rewrite the NestingThreshold logic without ab-using+mis-using that switch with fallthrough, and add testcases with nested `if`' where there should be a warning and shouldn't be a warning. This results in a cleaner, simpler code, too.

I guess, now it would be actually possible to pick some reasonable default for `NestingThreshold` setting.

Fixes PR33454.

Roman Lebedev a1cee29608 [clang-tidy] readability-function-size: add NestingThreshold param. 
Summary:
Finds compound statements which create next nesting level after `NestingThreshold` and emits a warning.
Do note that it warns about each compound statement that breaches the threshold, but not any of it's sub-statements, to have readable warnings.

I was able to find only one coding style referencing nesting:
  - https://www.kernel.org/doc/html/v4.10/process/coding-style.html#indentation
     > In short, 8-char indents make things easier to read, and have the added benefit of warning you when you’re nesting your functions too deep.

This seems too basic, i'm not sure what else to test. Are more tests needed?

Summary:
New checker to replace dynamic exception
specifications

This is an alternative to D18575 which relied on reparsing the decl to
find the location of dynamic exception specifications, but couldn't
deal with preprocessor conditionals correctly without reparsing the
entire file.

This approach uses D20428 to find dynamic exception specification
locations and handles all cases correctly.

Summary:
Single-line if statements cause a false positive when the last token in the conditional statement is a char constant:

```
if (condition)
  return 'a';

For some reason `findEndLocation` seems to skips too many (vertical) whitespaces in this case. The same problem already occured with string literals (https://reviews.llvm.org/D25558), and was fixed by adding a special check for this very case. I just extended the condition to also include char constants. No idea what really causes the issue though.

Alexander Kornienko 6180337fe1 [clang-tidy] Optimize GlobList::contains 
With large lists of checks and large number of warnings GlobList::contains
