VerifyDiagnosticConsumer previously would not check that the diagnostic and
its matching directive referenced the same source file. Common practice was
to create directives that referenced other files but only by line number,
and this led to problems such as when the file containing the directive
didn't have enough lines to match the location of the diagnostic in the
other file, leading to bizarre file formatting and other oddities.
This patch causes VerifyDiagnosticConsumer to match source files as well as
line numbers. Therefore, a new syntax is made available for directives, for
example:
// expected-error@file:line {{diagnostic message}}
This extends the @line feature where "file" is the file where the diagnostic
is generated. The @line syntax is still available and uses the current file
for the diagnostic. "file" can be specified either as a relative or absolute
path - although the latter has less usefulness, I think! The #include search
paths will be used to locate the file and if it is not found an error will be
generated.
The new check is not optional: if the directive is in a different file to the
diagnostic, the file must be specified. Therefore, a number of test-cases
have been updated with regard to this.
This closes out PR15613.

cout << x == 0;
which the compiler will intrepret as
(cout << x) == 0;
This warning comes with two fixits attached to notes, one for parentheses to
silence the warning, and another to evaluate the comparison first.

Add CapturedDecl to be the DeclContext for CapturedStmt, and perform semantic

Invalid redeclarations of valid explicit declarations shouldn't
take the same path as redeclarations of implicit declarations,
and invalid local extern declarations shouldn't foul things up
for everybody else.

We had been defining Neon intrinsics as "static" with always_inline attributes.
If you use them from an extern inline function, you get a warning, e.g.:
static function 'vadd_u8' is used in an inline function with external linkage
This change simply adds the inline keyword to avoid that warning.

These run lines originally tested that the fix-its were properly applied.
Originally, the fixits were attached to warnings and were applied by -fixit.
Now, the fixits are attached to notes, so nothing happens. These run lines
still manage to pass since Clang will produce an empty output which gets piped
back to Clang. Then Clang produces no error on an empty input.

caching the linkage for a declaration before we set up its redeclaration chain,
when determining whether a declaration could be a redeclaration of something
from an unimported submodule. We actually want to look at the declaration as if
it were not a redeclaration here, so compute the linkage but don't cache it.

variable in a C99 inline (but not static-inline or extern-inline)
function definition.
The standard doesn't actually say that this doesn't apply to
"extern inline" definitions, but that seems like a useful extension,
and it at least doesn't have the obvious flaw that a static
mutable variable in an externally-available definition does.
