Testing with a full OpenCL compiler (based on clang) reveals r71734 missed
difference between type widths of a vector and the width of one of its elements
in the case of vector shifts. Use correct witdth in the vector case.

r172047 lacked a test (due to incomplete OpenCL support in clang). Use a modified
version of a test by Joey Gouly to use attributes to materialise the unsupported
types and test vector shifts.

Improve clang-format's understanding of casts.

This fixes llvm.org/PR14684.

Before: int *pa = (int *) & a;
After:  int *pa = (int *)&a;

We still don't understand all kinds of casts. I added a FIXME to
address that.

Fix layout of blocks inside statements.

Previously, we would not indent:
SOME_MACRO({
  int i;
});
correctly. This is fixed by adding the trailing }); to the unwrapped
line starting with SOME_MACRO({, so the formatter can correctly match
the braces and indent accordingly.

Also fixes incorrect parsing of initializer lists, like:
int a[] = { 1 };

[Mips] Pass a combination of +soft-float and -mips16-hard-float flags to

Improvements to function type and ObjC block formatting.

Before: int (^myBlock) (int) = ^(int num) {}
        A<void ()>;
	int (*b)(int);

After:  int (^myBlock)(int) = ^(int num) {}
        A<void()>;
	int(*b)(int);

For function types and function pointer types, this patch only makes
the behavior consistent (for types that are keywords and other types).
For the latter function pointer type declarations, we'll probably
want to add a space after "int".

Also added LangOpts.Bool = 1, so we handle "A<bool()>" appropriately
Moved the LangOpts-settings to a public place for use by tests
and clang-format binary.

Fixes formatting of function calls etc inside an initializer list.

We're now formatting (column limit 25):
int x = {
  avariable,
  b(alongervariable) };

This also fixes:
Aaa({
  int i;
}, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb,
                                    ccccccccccccccccc));
... where we would previously break after the '},'.

Putting the closing curly into an extra line when there's a break
directly after the first curly will be done in a subsequent patch.

Paired with djasper.

Fixes layout of right braces.

We now decide whether a newline should go before the closing brace
depending on whether a newline was inserted after the opening brace.

For example, we now insert a newline before '};' in:
static SomeClass WithALoooooooooooooooooooongName = {
  100000000, \"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\"
};
... while not inserting a newline here:
static SomeClass = { a, b, c, d, e, f, g, h, i, j,
                     looooooooooooooooooooooooooooooooooongname,
                     looooooooooooooooooooooooooooooong };

Also fixes the formating of (column limit 25):
int x = {
  avariable,
  b(alongervariable)
};

Pulling formatFirstToken one level up.

This prepares the code for single line optimizations and changes the
dependencies between single-line-formats to the indent of the first
token.

Conceptually, the first token is "between" the lines anyway, as the
whitespace for the first token includes the previous end-of-line, which
needs to be escaped when inside a preprocessor directive.

Error if an anonymous DiagGroup is referenced multiple times.

Not only is this inefficient for TableGen, it's annoying for maintenance
when renaming warning flags (unusual) or adding those flags to a group
(more likely).

This uses the new fix-it infrastructure for LLVM's SourceMgr/SMDiagnostic,
as well as a few changes to TableGen to track more source information.

Diagnostics: name all implicit groups used more than once.

This will be a new style requirement going forwards: a diagnostic can only
use the implicit InGroup<DiagGroup<"foo">> syntax if "foo" is not used by
any other diagnostics; as soon as it is, it needs an explicit group.

This also brings some stray "conversion" diagnostics into the
"Value Conversion Issue" category, instead of the more generic
"Semantic Issue" category. I consider this an improvement!
