Add configure infrastructure (--with-llvm) to enable LLVM support.

Browse Source 
LLVM will be used for *optional* Just-in-time compilation
support. This commit just adds the configure infrastructure that
detects LLVM.

No documentation has been added for the --with-llvm flag, that'll be
added after the actual supporting code has been added.
