Minimal build fixes for OpenBSD

LLVM 2.1 doesn't install out of the box on OpenBSD-currend amd64. The minimum
fixes needed to fix things for me are:

 1) include/llvm/Pass.h doesn't know about intptr_t. Quick hack: include
    stdint.h. There's probably a more idiomatic way of fixing this.

 2) include/llvm/ADT/DenseMap.h uses new style C++ casts which GCC 3.3.5
doesn't
    understand. Revert a previous patch which added these (nowhere else in the
    code base seems to have this problem).

 3) Makefile.rules tries to install files as root during the normal build
    process (i.e. before "make install"). This then causes an error for
    LLVMHello. I've hacked this so that in the offending rule, install is
    only called if the compiler target is itself install. I suspect this
    is not OpenBSD specific, and would affect anyone who compiles as a
    normal user, calling only "make install" as root.
