gcc doesn't support "gcc -m sse" and this was not tested in clang and only
used for link argument on darwin, so this was very likely just a bug.

This solves two problems:
1) MSBuild will not flag the build as unsuccessful just because we print
an error in the output, since "error(clang):" doesn't seem to match
the regex it's using.
2) It becomes more clear that the diagnostic is coming from clang as
supposed to cl.exe.

This doesn't change a lot since clang still thinks it knows all of the
-f*, -m* and -W* options for example.
Other than the options clang explicitly claims to know, this fixes pr9701.

Summary:
We enable ASAN's use-after-return instrumentation at compile-time,
but still keep it disabled at run-time.
This enables the users to flip the flag at run-time using environment variable
ASAN_OPTIONS=detect_stack_use_after_return=1 instead of using a separate build.
If UAR detection is disabled at run-time, this extra compile-time instrumentation
costs very small slowdown. On SPEC 2006 14 tests are not affected at all,
4 tests get ~ 1% slowdown and 453.povray gets 4%.

Summary:
Parsing cast expressions during error recovery can put us in a bad
state. Check to see if the token for a simple-type-specifier makes
sense before further parsing.
Fixes PR17255.

This solves the problem of fallback onto ourselves if clang-cl
has been renamed to cl.exe and put on the PATH, as happens with
the VS integration.

Apart from being more compact and already implemented, this also handles the
case where the parent is null. (It does also ignore all casts, not just
implicit ones, but this is more efficient to test and in the case we care
about---a message in a PseudoObjectExpr---there should only be implicit casts
anyway.
This should fix our internal buildbot.

Instead add the ASan runtime to the linker command line so that only the ASan API functions can be undefined in the target library.

fields in the class. This allows a better checking of member intiailizers and
in class initializers in regards to initialization ordering.
For instance, this code will now produce warnings:
class A {
int x;
int y;
A() : x(y) {} // y is initialized after x, warn here
A(int): y(x) {} // default initialization of leaves x uninitialized, warn here
};
Several test cases were updated with -Wno-uninitialized to silence this warning.

variable from being the function to being the enclosing namespace scope (in
C++) or the TU (in C). This allows us to fix a selection of related issues
where we would build incorrect redeclaration chains for such declarations, and
fail to notice type mismatches.
Such declarations are put into a new IdentifierNamespace, IDNS_LocalExtern,
which is only found when searching scopes, and not found when searching
DeclContexts. Such a declaration is only made visible in its DeclContext if
there are no non-LocalExtern declarations.

_Bool in C, if the macro is defined. Also teach FixItUtils to look at whether
the macro was defined at the source location for which it is creating a fixit,
rather than looking at whether it's defined *now*. This is especially relevant
for analysis-based warnings which are delayed until end of TU.

When -fms-extensions is enabled, the typo correction was being called here on
non-error paths (as in test/SemaTemplate/lookup-dependent-bases.cpp) and correct

When this flag is enabled, clang-cl falls back to cl.exe if it
cannot compile the code itself for some reason.
The idea is to use this to help build projects that almost compile
with clang-cl, except for some files that can then be built with
the fallback mechanism.
