Add shared and rtti options to LLVM.

Browse source 
* Added a --shared option to build LLVM as a shared library.
  (Shouldn't be used with --universal as it will cause the build to fail)

* Added a --rtti option to build LLVM with RTTI information.
  (Can be used, for example, to build LLVM for use with Rubinius)

Closes Homebrew/homebrew#3847.
