Clang relies on existence of certain symbols that are normally provided by crtbegin.o/crtend.o. However, LLVM does not currently provide implementation of these files, instead relying on either libgcc or implementations provided as part of the system. This change provides an initial implementation of crtbegin.o/crtend.o that can be used on system that don't provide crtbegin.o/crtend.o as part of their C library.
