AliasAnalysis: unify getModRefInfo(I, CS) semantics with other overloads
This subtle change to getModRefInfo(Instruction, ImmutableCallSite) is to
ensure that the semantics are equal to that of getModRefInfo(CS1, CS2) when
the Instruction is a call-site.
This is now more in line with getModRefInfo generally: it returns Mod when
I modifies a memory location that is accessed (read or written) by CS and
Ref when I reads a memory location that is written by CS.
From a grep of the code, the only uses of this particular getModRefInfo
overload are in MemorySSA and MemCpyOptimizer, and they only care about
where the result is MR_NoModRef or not. Therefore, this change should have
no visible effect.

Sanitizers will have their C++ dependency satisfied internally (LC_LOAD_DYLIB)

We are currently using add_llvm_utility for executable targets that:
1. Are built by default.
2. Used for testing.
3. Are not installed by default.
Originally, lli-child-target used add_llvm_tool instead of add_llvm_executable
directly. This was changed so that lli-child-target would not be installed. This
was good since this is only used for testing and should never be installed for
users. This also had the unfortunate side effect that one can never turn off the

default do not want to compile any LLVM tools beyond tablegen/llvm-config.

1. lli-child-target matches the semantics of executables created with
add_llvm_utility.

[SCCP] Rename undefined -> unknown.
In the solver, isUndefined() does really mean "we don't know the
value yet" rather than "this is an UndefinedValue". Discussed with

This code was already commented out and it made some weird assumptions,
e.g. using isUndefined() as "this value is UndefValue" instead of

MASM (ML.exe and ML64.exe) and older versions of MSVC (CL.exe) support a

test: Use %clangxx in objc++ test files
These test in this change are objc++, but are built using %clang, not %clangxx.
The reason this works is the driver has been adding -lc++ for sanitizer enabled
builds. By making these tests use %clangxx, they no longer depend on the driver
linking to c++. Doing so will allow us to prevent overlinking of libc++ for
applications.
