Port to LLVM 3.3
Major changes are: - Switching to llvm-link to build archive files - Use GetMallocUsage instead of GetTotalMemoryUsage (be aware of bug in LLVM 3.3 http://llvm.org/bugs/show_bug.cgi?id=16847) - intrinsic library functions like memcpy/mov/set use weak linkage to be replaced by e.g. uclibc functions - rewrote linking with library - enhanced MemoryLimit test case to check if mallocs were successful
