Fixes PR30847. Partially fixes PR20973 (first position only).
PR17614 is still not working, its expression has the dependent
builtin type. We'll have to teach the completion engine how to "resolve"
dependent expressions to fix it.

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.

Diagnostics related to redefinition errors that point to the same header
file do not provide much information that helps users fixing the issue.
- In the modules context, it usually happens because of non modular
includes.
- When modules aren't involved it might happen because of the lack of
header guards.
Enhance diagnostics in these scenarios.

When an undeclared identifier in a context that requires a type is followed by
'<', only look for type templates when typo-correcting, tweak the diagnostic
text to say that a template name (not a type name) was undeclared, and parse
the template arguments when recovering from the error.

As discovered by ChenWJ and listed on cfe-dev, the error for Objective C
return type ended up being wrong. This fixes that. Additionally, as a
"while we're there", the other usages of this error and the usage of the
FP above both use a FixItHint, so I'll add it here.

Green dragon had a green stage2 modules bot for a long time now[1] and
it is time to retire it and make a modules build the default for
Apple-style stage2 builds.
This patch switches the debug info generation from -gline-tables-only
to -g since full debug info does no longer cause any memory issues
even for full LTO builds [2].

with minor changes (use regexp instead of the hardcoded values) to the test.
llvm-svn: 302670
Summary:
For C++ code, opening parenthesis following a } indicate a braced init. For JavaScript and other languages, this is an invalid syntactical construct, unless the closing parenthesis belongs to a function - in which situation its a BK_Block.
This fixes indenting IIFEs following top level functions:
function foo() {}
(function() { codeHere(); }());
clang-format used to collapse these lines together.

The heuristic that we use here is:
* the left-hand side must be a simple identifier or a class member access
* the right-hand side must be '<' followed by either a '>' or by a type-id that
cannot be an expression (in particular, not followed by '(' or '{')
* there is a '>' token matching the '<' token
The second condition guarantees the expression would otherwise be ill-formed.
If we're confident that the user intended the name before the '<' to be
interpreted as a template, diagnose the fact that we didn't interpret it
that way, rather than diagnosing that the template arguments are not valid
expressions.

Sanitizer instrumentation generally needs to be marked with !nosanitize,
but we're not doing this properly for ubsan's overflow checks.
r213291 has more information about why this is needed.
llvm-svn: 302598
This improves our behavior in a few ways:
* We now guarantee that if a member is marked as being a member
specialization, there will actually be a member specialization declaration
somewhere on its redeclaration chain. This fixes a crash in modules builds
where we would try to check that there was a visible declaration of the
member specialization and be surprised to not find any declaration of it at
all.
* We don't set the source location of the in-class declaration of the member
specialization to the out-of-line declaration's location until we have
actually finished merging them. This fixes some very silly looking
diagnostics, where we'd point a "previous declaration is here" note at the
same declaration we're complaining about. Ideally we wouldn't mess with the
prior declaration's location at all, but too much code assumes that the
first declaration of an entity is a reasonable thing to use as an indication
of where it was declared, and that's not really true for a member
specialization unless we fake it like this.

This feature is subtly broken when the linker is gold 2.26 or
earlier. See the following bug for details:
https://sourceware.org/bugzilla/show_bug.cgi?id=19002
Since the decision needs to be made at compilation time, we can not
test the linker version. The flag is off by default on ELF targets,
and on otherwise.

Because IIFEs[1] are often used like an anonymous namespace around large
sections of JavaScript code, it's useful not to indent to them (which
effectively reduces the column limit by the indent amount needlessly).
It's also common for developers to wrap these around entire files or
libraries. When adopting clang-format, changing the indent entire file
can reduce the usefulness of the blame annotations.
