Title: Ability to point build to custom version of llvm and clang

The way it was before, the makefile would automatically just search the PATH for llvm-config and use that one.

This is inconvenient if you build your own version of llvm and don't have the admin rights to install it. With this, you can build ispc with llvm and clang arbitrarily located. There's a couple of variables at the top of the Makefile which can be easily modified to point to any llvm and any clang includes.

By default, it works exactly the same as the original Makefile.
