PR13529: Don't crash if the driver sees an unused input file when running as

'clang-cpp'.
For now, the test uses "REQUIRES: shell" to determine if the host system
supports "ln -s", which it uses to create a 'clang-cpp' symlink. This is a bit
hacky and should likely be directly supported by lit.cfg.

Andrew Morrow: The current CMake setup for libc++ incorrectly uses the variable
...
LLVM_ENABLE_ASSERTIONS instead of LIBCXX_ENABLE_ASSERTIONS when
figuring out what _DEBUG/NDEBUG defines to set. It also tries to test
the non-existent variable 'uppercase_CMAKE_BUILD_TYPE', which the top
level LLVM CMakeLists.txt sets up, but which the top level libc++
CMakeLists.txt currently does not. Changing the variable name tested
and creating the uppercase release name variable allows libc++ to
honor the LIBCXX_ENABLE_ASSERTIONS option correctly.

[analyzer] Don't assume values bound to references are automatically non-null.
...
While there is no such thing as a "null reference" in the C++ standard,
many implementations of references (including Clang's) do not actually
check that the location bound to them is non-null. Thus unlike a regular
null dereference, this will not cause a problem at runtime until the
reference is actually used. In order to catch these cases, we need to not
prune out paths on which the input pointer is null.

Refactor and check "onlyReadsMemory" before optimizing builtins.

This patch is mostly just refactoring a bunch of copy-and-pasted code, but
it also adds a check that the call instructions are readnone or readonly.
That check was already present for sin, cos, sqrt, log2, and exp2 calls, but
it was missing for the rest of the builtins being handled in this code.
