When the command line target options were removed from the LLVM libraries, LTO
lost its ability to specify things like `-disable-fp-elim'. Add this back by
adding the command line variables to the `lto' project.

No functionality change, but from now on, any new path notes should be
tested both with plain-text output (for ease of human auditing) and with
plist output (to ensure control flow and events are being correctly
represented in Xcode).

The frameworks correctly use the 'cf_consumed' and 'ns_returns_retained'
attributes for NSMakeCollectable, but we can model the behavior under
garbage collection more precisely than that.

No functionality change.

These 2 relocations gain access to the 
highest and the second highest 16 bits
of a 64 bit object.

R_MIPS_HIGHER %higher(A+S)
The %higher(x) function is [ (((long long) x + 0x80008000LL) >> 32) & 0xffff ]. 

R_MIPS_HIGHEST %highest(A+S)
The %highest(x) function is [ (((long long) x + 0x800080008000LL) >> 48) & 0xffff ].

The MFTB instruction itself is being phased out, and its functionality
is provided by MFSPR. According to the ISA docs, using MFSPR works on all known
chips except for the 601 (which did not have a timebase register anyway)
and the POWER3.

Thanks to Adhemerval Zanella for pointing this out!

Doxygen manual claims that multiple \brief or \returns commands will be merged
together, but actual behavior is different (second \brief command becomes a
part of a discussion, second \returns becomes a "Returns: blah" paragraph on
its own).  Anyway, it seems to be a bad idea to use multiple \brief or \returns
commands in a single command.

Use the built in demangler for Apple builds for now which has needed demangling fixes, and make the cxa_demangle.cpp use rtti in the Xcode project settings as it requires it be enabled.

Implement proper handling for pcmpistri/pcmpestri intrinsics. Requires custom handling in DAGISelToDAG due to limitations in TableGen's implicit def handling. Fixes PR11305.

'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.

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.

On PPC64, this can be done with a simple TableGen pattern.
To enable this, I've added the (otherwise missing) readcyclecounter
