When using __builtin_ctzll() in AArch32 code, the compiler may translate that into a call to the __ctzdi2() function. In this case, the linking phase fails because TF doesn't provide an implementation for it. This patch imports the implementation of the __ctzdi2() function from LLVM's compiler-rt project and hooks it into TF's build system. The ctzdi2.c file is an unmodified copy from the master branch as of July 19 2017 (SVN revision: 308480).
