Initial configure support for using Clang as the LLVM capable compiler.
Comes in two parts:
1. Use --with-clang=path/to/clang/compiler to select an installed clang, or
--with-built-clang to have the makefiles use the clang which will be built
as the LLVM capable compiler. If neither is given, --with-built-clang will
be used if the Clang sources are checked out into the standard location
(tools/clang).
2. Use --with-llvmcc={llvm-gcc,clang,none} to specify which LLVM capable
compiler to use. If not given, then llvm-gcc will be used if available,
otherwise Clang.
Makefile support still to come.

Mark the return address stack slot as mutable when moving the return address
during a tail call. A parameter might overwrite this stack slot during the tail
call.
The sequence during a tail call is:
1.) load return address to temp reg
2.) move parameters (might involve storing to return address stack slot)
3.) store return address to new location from temp reg
If the stack location is marked immutable CodeGen can colocate load (1) with the
store (3).
