This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

mess as functions were moved around into a better ordering. The code was
extended to provide various -gen-* options to better control what the
generated output should be. Currently it is possible to generate entire
modules (three different ways), functions, global variables, and types.

a floating point conversion problem with NAN in intrinsics.ll. llvm2cpp
makes an attempt to provide the correct conversion, based on the
implementation in the CBackend writer, but it doesn't get NAN correct.

1. Get rid of old AsmWriter cruft that's not needed.
2. Implement several instructions. Enough to get by globalvars.ll and
alignment.ll in the Feature test suite.
3. Handle constants properly (don't repeat definitions).
4. Make the output compatible with llvm-dis for diff purposes.

This is a safekeeping commit. The program is not finished. It currently
handles modules, types, global variables and function declarations. Blocks
and instructions remain to be done.
