Update OptimizeGlobalAddressOfMalloc() to optimize malloc calls that have non-bitcast uses.  The bitcast use of a malloc call has to be treated specially here because the uses of the bitcast need to be replaced and the bitcast needs to be erased (just like the malloc call) for OptimizeGlobalAddressOfMalloc() to work correctly.

Update PerformHeapAllocSRoA() to optimize malloc calls that have non-bitcast uses.  The bitcast use of the malloc is not handled specially here because ReplaceUsesOfMallocWithGlobal replaces through the bitcast use.

Run the functionattrs pass after the inliner, and not before.

-inline -functionattrs then @f is marked readnone because the
simplifications produced by the inliner eliminate the store.

CMake: Report an error if there is an unknown .cpp file in a source
directory.

This is useful in case someone who works with the config&make build
system forgot to add a file to its CMakeLists.txt. Instead of
obtaining undefined references at link time, cmake will complain at
configure time on the first build after a svn update.
