This fixes clang-format not formatting if fallback-style is explicitly set to
"none", and either a config file is found or YAML is passed in without a
"BasedOnStyle". With this change, passing "none" in these cases will have no
affect, and LLVM style will be used as the base style.

Change the contract of GetStyle so that it returns an error when an error occurs
(i.e. when it writes to stderr), and only returns the fallback style when it
can't find a configuration file.

Summary: Change r291428 introduced ASI detection after closing curly braces. That would generally be correct, however this breaks indentation for structural statements. What happens is that CompoundStatementIndenter increases indentation for the current line, then after reading ASI creates a new line (with the increased line level), and only after the structural parser sees e.g. the if/then/else branch closed, line level is reduced. That leads to the new line started by ASI having a level too high.

Here, the optimization to not line wrap when it would not lead to a
reduction in columns was overwriting and enforced break that we want to
do no matter what.
Before:
int i = someFunction(
aaaaaaa,
0).aaa(aaaaaaaaaaaaa) *
aaaaaaa +
aaaaaaa;
After:
int i = someFunction(aaaaaaa, 0)
.aaa(aaaaaaaaaaaaa) *
aaaaaaa +
aaaaaaa;

Specifically, wrap before them if they are multi-line so that we don't
create long hanging indents. This prevents having a lot of code
indented a lot in some cases.

List3});
After:
someFunction(Param,
{List1, List2,
List3});

Summary:
We do not currently track the source locations for exception specifications such
that their source range can be queried through the AST. This leads to trying to
write more complex code to determine the source range for uses like FixItHints
(see D18575 for an example). In addition to use within tools like clang-tidy, I
think this information may become more important to track as exception
specifications become more integrated into the type system.

Summary:
Automatic semicolon insertion should break import and export statements:
Before, this would format on one line:
// Note: no semi after 'x' below!
import {x} from 'x'
export function foo() {}
Into:
import {x} from 'x' export function foo() {}
With this change, the statements get separated.
This also improves automatic semicolon insertion to consider closing
braces preceding declarations and statements.

Aleksey Shlypanikov pointed out my mistake in migrating an explicit
unique_ptr to auto - I was expecting the function returned a unique_ptr,
but instead it returned a raw pointer - introducing a leak.
Thanks Aleksey!

The problem was that clang-format would unconditionally try to parse a child block, even though ambient function declarations do not have a body (similar to forward declarations).

implementation; we retain the restriction that the argument must not be

Modify getStyle to use vfs::FileSystem::makeAbsolute just like FS.addFile does,
rather than sys::fs::make_absolute. The latter gets the CWD from the platform,
while the former expects it to be set by the client, causing a mismatch when
converting relative paths to absolute.

While for <<-operators often used in log statments, a single key value
pair is always on the second operator, e.g.
llvm::errs() << "aaaaa=" << aaaaa;
It is on the first operator for plus- or comma-concatenated strings:
string s = "aaaaaaaaaa: " + aaaaaaaa;
(the "=" not counting because that's a different operator precedence)

Single-column layout basically means that we format the list with one

doesn't change the fact that there is an item that doesn't fit within
the column limit.

std::vector<int> a = {

While C(++) and ObjC are generally formatted the same way and can be
mixed, people might want to choose different styles based on the
language. This patch recognizes .m and .mm files as ObjC and also
implements a very crude detection of whether or not a .h file contains
ObjC code. This can be improved over time.
Also move most of the ObjC tests into their own test file to keep file
size maintainable.

In bigger projects like an Operating System, the same source code is
often compiled in slightly different ways. This could be the difference
between PIC and non-PIC code for static vs dynamic libraries, it could
also be the difference between size optimised versions of tools for
ramdisk images. At the moment, the compilation database has no way to
distinguish such cases. As first step, add a field in the JSON format
for it and process it accordingly.
