llvm-ar manual page:
http://llvm.org/cmds/llvm-ar.html
I think the major difference is that llvm-ar is aimed for bitcode (.bc)
files, same as other llvm-xxx tools. (for example, llvm-ld)
Other that that, llvm-ar uses a different symbol table, a different
compression solution. (llvm-ar compresses each member separately, not
the entire archive, this is probably better wrt random access of
members?). llvm-ar also has a handy -R option which we should
probably add to our ar(1).
And from what I read in the wiki, it looks like llvm-ld can be used as
long as --emit-llvm is specified when compiling?
