For PR496:
When llvm-gcc is not available, bypass rules for Modules and Bytecode
Libraries that require llvm-gcc and emit instead a warning that llvm-gcc
is not available. This permits "make LLVMGCC=" to build LLVM completely
without error and provides warnings about the modules and bc libs that
could not be constructed.

Print GEP offsets as signed values instead of unsigned values.  On X86, this

assembler much happier.

This fixes test/Regression/CodeGen/X86/2005-02-14-IllegalAssembler.ll,
