Codegen failure for vmull with small vectors
Codegen was failing with an assertion because of unexpected vector
operands when legalizing the selection DAG for a MUL instruction.
The asserting code was legalizing multiplies for vectors of size 128
bits. It uses a custom lowering to try and detect cases where it can
use a VMULL instruction instead of a VMOVL + VMUL. The code was
looking for input operands to the MUL that had been sign or zero
extended. If it found the extended operands it would drop the
sign/zero extension and use the original vector size as input to a
VMULL instruction.
The code assumed that the original input vector was 64 bits so that
after dropping the extension it would fit directly into a D register
and could be used as an operand of a VMULL instruction. The input
code that trigger the failure used a vector of <4 x i8> that was
sign extended to <4 x i32>. It was not safe to drop the sign
extension in this case because the original vector is only 32 bits
wide. The fix is to insert a sign extension for the vector to reach
the required 64 bit size. In this particular example, the vector would
need to be sign extented to a <4 x i16>.

Use the new LLVM_LVALUE_FUNCTION to ban two getAs() calls on rvalues.
If 'x' is a temporary, x.getAs<Foo>() may not be safe if the result is
supposed to persist (if its address is stored somewhere). Since getAs()
can return a null value, the result is almost always stored into a
variable, which of course is not safe when the original value dies.
This has caused several bugs with GCC's "Temporaries May Vanish Sooner Than
You Expect" optimization; in C++11 builds, at least, we'll be able to catch
these problems now.
I would suggest applying these to other getAs() and get*As() methods

means the temporary will still be live), but these two have both caused

Add a new C++11 compatibility macro, LLVM_LVALUE_FUNCTION.
This expands to '&', and is intended to be used when an /optional/ rvalue
override is available.
Before:
void foo() const { ... }
After:
void foo() const LLVM_LVALUE_FUNCTION { ... }
void foo() && { ... }
This is used to allow moving the contents of an Optional.

Keep track of modules that have failed to build. If we encounter an
import of that module elsewhere, don't try to build the module again:
it won't work, and the experience is quite dreadful. We track this
information somewhat globally, shared among all of the related
CompilerInvocations used to build modules on-the-fly, so that a
particular Clang instance will only try to build a given module once.
Fixes <rdar://problem/

ubsan: Disable __int128 tests if the host Clang does not support it. These
tests will still fail if compiler-rt was built with a compiler without __int128

[ASan] use brand new -fsanitize= values for init-order/use-after-return ASan output tests

This patch exposes to Clang users three more sanitizers are experimental features of ASan:
1) init-order sanitizer: initialization-order checker.
Status: usable, but may produce false positives w/o proper blacklisting.
2) use-after-return sanitizer
Status: implemented, but heavily understed.
Should be optional, as it significanlty slows program down.
3) use-after-scope sanitizer
Status: in progress.

Emit an error when using "target modules add PATH" where PATH points to a debug info only (dSYM) file.
Also added a "--uuid" option for "target modules add --uuid UUID" to locate and load a module by UUID if the host supports it.
