813b8a9e89 Add an implementation of __ffssi2() derived from __ffsdi2(). 
Newer versions of GCC include an __ffssi2() symbol in libgcc and the
compiler can emit calls to it in generated code.  This is true for at
least GCC 6.2 when compiling world for mips and mips64.

040b30497c libcompiler_rt: move file list to Makefile.inc for reuse elsewhere 
Also switch to the style used in the clang390-import branch to reduce
future conflicts.
