Evan Cheng 18381b4257 Add intrinsics @llvm.arm.neon.vmulls and @llvm.arm.neon.vmullu.* back. Frontends 
was lowering them to sext / uxt + mul instructions. Unfortunately the
optimization passes may hoist the extensions out of the loop and separate them.
When that happens, the long multiplication instructions can be broken into
several scalar instructions, causing significant performance issue.

Note the vmla and vmls intrinsics are not added back. Frontend will codegen them
as intrinsics vmull* + add / sub. Also note the isel optimizations for catching
mul + sext / zext are not changed either.

First part of rdar://8832507, rdar://9203134

Jim Ingham 7572fa75cf Can't just call "rand" to get a random port, 'cause then you'll get the same sequence in two lldb's. This makes running lldb on lldb not work very well.

Oscar Fuentes 978e5284fa Fixed the build of Clang's unit tests on MinGW. Also removed some 
unnecesary conditionals and introduced a new convenience function.

The problem was that the list of libraries for Clang's unit tests was
<clang libraries> <system libraries> <llvm libraries>. As the llvm
libraries references symbols defined on the system libraries, those
were reported as undefined.

Chandler Carruth ffce245700 Fix a bug in how we were resolving the address of overloaded functions 
when the resolution took place due to a single template specialization
being named with an explicit template argument list. In this case, the
"resolution" doesn't take into account the target type at all, and
therefore can take place for functions, static member functions, and
*non-static* member functions. The latter weren't being properly checked
and their proper form enforced in this scenario. We now do so.

The result of this last form slipping through was some confusing logic
in IsStandardConversion handling of these resolved address-of
expressions which eventually exploded in an assert. Simplify this logic
a bit and add some more aggressive asserts to catch improperly formed
expressions getting into this routine.

Finally add systematic testing of member functions, both static and
non-static, in the various forms they can take. One of these is
essentially PR9563, and this commit fixes the crash in that PR. However,
the diagnostics for this are still pretty terrible. We at least are now
accepting the correct constructs and rejecting the invalid ones rather
than accepting invalid or crashing as before.
