Parser::ParseNamespace can get a little confused when it found itself
inside a compound statement inside of a non-static data member
initializer.
Try to determine that the statement expression's scope makes sense
before trying to parse it's contents.

We assumed that class-scope specializations would result in a
CXXMethodDecl for that class. However, globally qualified functions
will result in normal FunctionDecls.

Sema::CheckParmsForFunctionDef can't cope with a null TypeSourceInfo.
Don't let the AST contain the malformed lambda.
This fixes PR22122.

Allow blessed access to the symbol rewriter from the driver. Although the
symbol rewriter could be invoked through tools like opt and llc, it would not
accessible from the frontend. This allows us to read the rewrite map files in
the frontend rather than the backend and enable symbol rewriting for actually
performing the symbol interpositioning.

We were previously emitting counter increments even if we didn't have
an insertion point, which would result in a CallInst with no
parent. This leads to a crash, as in pr22166, if we try to do
GlobalDCE.

We forgot to mark designated initializer expression that contain type
dependent array designators as type dependent. This would lead to
crashes when we try to determine which array element we were trying to
initialize.
This fixes PR22056.

we're instantiating, if there's a ParmVarDecl within a FunctionDecl context
that is not a parameter of that function. Add some asserts to catch this kind
of issue more generally, and fix another bug exposed by those asserts where we
were missing a local instantiation scope around substitution of
explicitly-specified template arguments.

better than the 'template-parameter-x-y' name that we'd get in AST printing,
and is worse in several ways (it's harder to distinguish it from a
user-supplied name, it's wrong after substituting some number of outer
levels, it wastes time and space constructing an IdentifierInfo, ...).

- includes header/footer as required by MELPA
- correctly handles buffers that are not associated with a file
- displays stderr and exit code of clang-format process
- customizable via the emacs customization interface and file-/directory-
local variables

This makes piped output easier to read in many instances.
Before:
llvm::errs() << aaaa << std::endl << bbbb << std::endl;
After:
llvm::errs() << aaaa << std::endl
<< bbbb << std::endl;
Also fix a few instance of "don't use else after return" as per the
coding standards.

If there are some non-ascii character in the input source code, the
column index might be smallar than the byte index. This will result
in two possible assertion failures. This CL fixes the computation of
the column index and byte index.
1. The assertion in startOfNextColumn() and startOfPreviousColumn()
should not be raised when the byte index is greater than the column
index since the non-ascii characters may use more than one bytes to
store a character in a column.
2. The length of the caret line should be equal to the number of columns
of source line, instead of the length of the source line. Otherwise,
the assertion in selectInterestingSourceRegion will be raised because
the removed columns plus the kept columns are not greater than the max
column, which means that we should not remove any column at all.

I keep forgetting the exact spelling of -macosx-version-min=, and now I can
run `bin/clang --help | grep version -A 2` to remind myself. While here,
also document -mios-version-min=. Don't document -mios-simulator-version-min=
as it's just an alias for -mios-version-min= these days.

transform.
Also diagnose typos in the initializer of an invalid C++ declaration.
Both issues were hit using the same line of test code, depending on
whether the code was treated as C or C++.
Fixes PR22092.

Shorter and doesn't need -O2 -- but still suboptimal as it's still doing
-emit-obj. dblaikie says he'll improve this when he'll reland his change
with a fix.

r225141 changed the defaults of AllowShortIfStatementsOnASingleLine and
AlignTrailingComments for Google style and added explicit overrides for
Chromium style to undo these changes. For AllowShortIfStatementsOnASingleLine
that's good as the Android style guide (which Chromium uses for Java) explicitly
permits single-line ifs. But it's silent on trailing comments, to it makes
sense for Chromium style to just follow Google style.

PR22096 has several test cases that assert that look fairly different. I'm
adding one of those as an automated test, but when relanding the other cases
should probably be checked as well.

This prevents clang-format from moving/aligning the comment in the
snippet:
void f() {
int i; // some comment
// some unrelated comment
}

Add additional constraint checking for target specific behaviour for inline
assembly constraints. We would previously silently let all arguments through
for these constraints. In cases where the constraints were violated, we could
end up failing to select instructions and triggering assertions or worse,
silently ignoring instructions.

Summary:
Allow -fsanitize-coverage=N with ubsan, clang part.
This simply allows the flag combination.
The LLVM will work out of the box, the compile-rt part
will follow as a separate patch.

For some regression tests the path to the right toolchain is specified using the -sysroot switch. However, if clang was configured with a custom gcc toolchain (either by using GCC_INSTALL_PREFIX in cmake or the equivalent configure command), the path to the custom gcc toolchain path takes precedence to the one specified by sysroot. This causes several regression tests to fail as they will be using an unexpected path. This patch fixes this issue by adding --gcc-toolchain='' to all tests that rely on that. The empty string causes the driver to pick the path from sysroot instead.

Summary:
Replace usage of StringRef with std::string in AST_MATCHER* generated
matchers to make sure they keep their own copy of the string.
The value could be a temporary and it causes the pointer to be dangling
by the time the matcher is executed.
