preproc: Revert to the NASM 2.09 preprocessor

The NASM 2.09 preprocessor allows some illogical constructs, but which
unfortunately has been found in real code in the field.  We need
a compatibility solution or a pragma before we can avoid that.

However, we need the other features in NASM 2.10 to come out, so
revert the preprocessor changes for now.
