Krasimir Georgiev a2e7d0dee3 [clang-format] Do not format likely xml
Summary:
This patch detects the leading '<' in likely xml files and stops formatting in
that case. A recent use of a Qt xml file with a .ts extension triggered this:

Richard Smith 2563984215 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.

Francois Ferrand ad72256daa clang-format: add options to merge empty record body
Summary:
This patch introduces a few extra BraceWrapping options, similar to
`SplitEmptyFunction`, to allow merging empty 'record' bodies (e.g.
class, struct, union and namespace):
* SplitEmptyClass
* SplitEmptyStruct
* SplitEmptyUnion
* SplitEmptyNamespace

The `SplitEmptyFunction` option name has also been simplified/
shortened (from `SplitEmptyFunctionBody`).

These options are helpful when the correspond AfterXXX option is
enabled, to allow merging the empty record:

  class Foo
  {};

In addition, this fixes an unexpected merging of short records, when
the AfterXXXX options are used, which caused to be formatted like
this:

  class Foo
  { void Foo(); };

This is now properly formatted as:

  class Foo
  {
     void Foo();
  };

Chandler Carruth d676ab1354 [clang-format] Switch to case-insensitive header matching and use it to
improve support for LLVM-style include sorting.

This really is a collection of improvements to the rules for LLVM
include sorting:
- We have gmock headers now, so it adds support for those to one of the
  categories.
- LLVM does use 'FooTest.cpp' files to test 'Foo.h' so it adds that
  suffix for finding a main header.
- At times the test file's case may not match the header file's case, so
  switch to case-insensitive regex matching of header names.

With this set of changes, I can't spot any misbehaviors when re-sorting
all of LLVM's unittest '#include' lines.

Thanks to Eric and Daniel for help testing and refining the patch during
review!

Francois Ferrand d3f0e3dee0 clang-format: introduce InlineOnly short function style
Summary:
This is the same as Inline, except it does not imply all empty
functions are merged: with this style, empty functions are merged only
if they also match the 'inline' criteria (i.e. defined in a class).

This is helpful to avoid inlining functions in implementations files.

Also add a lot more test coverge for formatting things in LK_ObjC mode,

being tested for LK_Cpp at the moment.
