1. Rename android-file-open-flag to android-cloexec-open.
2. Handle a case when the function is passed as an argument of a function-like macro.

* Update docs to reflect D34269, which adds "Go To Declaration" functionality
llvm-svn: 306598
Summary: This change allows to navigate to most identifiers' declarations in code. This is a first step towards implementing "Go to Definition". It reuses clangIndex in order to detect which occurrences corresponds to the position requested. The occurrences' Decls are then used to generate locations suitable for navigating to the declarations.

llvm-svn: 306378
Summary:
A common source of security bugs is code that opens a file descriptors without using the O_CLOEXEC flag. (Without that flag, an opened sensitive file would remain open across a fork+exec to a lower-privileged SELinux domain, leaking that sensitive data.).
Add a new Android module and one checks in clang-tidy.
-- open(), openat(), and open64() should include O_CLOEXEC in their flags argument. [android-file-open-flag]

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

llvm-svn: 306091
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.

This function was previously making (correct) assumptions
without complete knowledge of MacroArgs guarantees for
Arguments. After going through Macro Args a bunch, I'd
corrected the getNumArguments (and changed its name),
however didn't realize this was depending on the behavior.
This patch has version that depends on the corrected
getNumMacroArguments's behavior, with the rest checked against
my knowledge of the MacroArgs' token list. Commiting no-wait
since the test is broken.

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:
This patch adds information about the parameters and return types of completion
candidates.
Previously, for the following code:
```
struct S {
int func(int a, double b) const;
};
```
the completer would only return the label of the candidate `func`.
Now it will also return the return type `int` and will format the label for the
candidate as `func(int a, double b) const`.

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.
