If the variable is marked as TLS variable and target device does not
support TLS, the error is emitted for the variable even if it is not
used in target regions. Patch fixes this and allows to use the values of
the TLS variables in target regions.

This is recommit of r302775, reverted in r302777 due to a fail in
clang-tidy. Original mesage is below.
Now if clang driver is given wrong arguments, in some cases it
continues execution and returns zero code. This change fixes this
behavior.
The fix revealed some errors in clang test set.
File test/Driver/gfortran.f90 added in r118203 checks forwarding
gfortran flags to GCC. Now driver reports error on this file, because
the option -working-directory implemented in clang differs from the
option with the same name implemented in gfortran, in clang the option
requires argument, in gfortran does not.
In the file test/Driver/arm-darwin-builtin.c clang is called with
options -fbuiltin-strcat and -fbuiltin-strcpy. These option were removed
in r191435 and now clang reports error on this test.
File arm-default-build-attributes.s uses option -verify, which is not
supported by driver, it is cc1 option.
Similarly, the file split-debug.h uses options -fmodules-embed-all-files
and -fmodule-format=obj, which are not supported by driver.
Other revealed errors are mainly mistypes.

Now FixedCompilationDatabase::loadFromCommandLine has no means to report
which error occurred if it fails to create compilation object. This is
a block for implementing D33013, because after that change driver will
refuse to create compilation if command line contains erroneous options.
This change adds additional argument to loadFromCommandLine, which is
assigned error message text if compilation object was not created. This is
the same way as other methods of CompilationDatabase report failure.

Summary:
This option replaces the BreakConstructorInitializersBeforeComma option with an enum, thus introducing a mode where the colon stays on the same line as constructor declaration:
// When it fits on line:
Constructor() : initializer1(), initializer2() {}
// When it does not fit:
Constructor() :
initializer1(), initializer2()
{}
// When ConstructorInitializerAllOnOneLineOrOnePerLine = true:
Constructor() :
initializer1(),
initializer2()

This change allows us to add arg1 logging support to functions through
the special case list provided through -fxray-always-instrument=. This
is useful for adding arg1 logging to functions that are either in
headers that users don't have control over (i.e. cannot change the
source) or would rather not do.
It only takes effect when the pattern is matched through the "fun:"
special case, as a category. As in:

Summary:
Sema creates a declaration for gro variable as:
auto $gro = $promise.get_return_object();
However, gro variable has to outlive coroutine frame and coroutine promise, but,
it can only be initialized after the coroutine promise was created, thus, we
split its emission in two parts: EmitGroAlloca emits an alloca and sets up
the cleanups. Later when the coroutine promise is available we initialize
the gro and set the flag that the cleanup is now active.

We currenltly assert when want to diagnose a missing import and the decl
in question is already visible. It turns out that the decl in question
might be visible because another decl from the same module actually made
the module visible in a previous error diagnostic.
Remove the assertion and avoid re-exporting the module if it's already
visible.

This avoids the possibility of a declaration being (meaninglessly) marked as
hidden with no owning module, which would otherwise lead to violated AST
invariants (checked by the added assertion).

C++14 added user-defined literal support for complex numbers so that you can
write something like "complex<double> val = 2i". However, there is an existing
GNU extension supporting this syntax and interpreting the result as a _Complex
type.
This changes parsing so that such literals are interpreted in terms of C++14's
operators if an overload is present but otherwise falls back to the original
GNU extension.

This test was failing on our fork of clang because it was not capturing
[[ARG]] in the N32 case. Therefore it used the value from the last function
which does not always have to be the same. All other cases were already
capturing ARG so this appears to be an oversight.
The test now uses -enable-var-scope to prevent such errors in the future.

When a diagnostic includes a highlighted range spanning multiple lines, clang
now supports printing out multiple lines of context if necessary to show the
highlighted ranges. This is not yet exposed in the driver, but can be enabled
by "-Xclang -fcaret-diagnostics-max-lines -Xclang N".
This is experimental until we can find out whether it works well in practice,
and if so, what a good default for the maximum number of lines is.
