The code that found a nearby data target for an instruction operand
was searching backward but not forward. We now take one step
forward, so that "LDA TABLE-1,Y" fills in automatically.
This altered 2008-address-changes, which had just this situation.
It didn't alter 2010-target-adjustment, but the existing tests were
insufficient and have been improved.
This worked, sort of. The problem is that SourceGen will revert to
hex output in certain situations, such as a broken symbolic
reference. There happens to be one in the ZIPPY example, and it's
on a relative branch.
The goal with the segment stuff is to allow cc65 to treat the
source as relocatable code. In that context, a relative branch to
an absolute address doesn't make any sense, so the assembler reports
a range error.
We don't currently have a mechanism that guarantees no references
are broken (and no affordance for finding them), so we can't make
this mode the default yet.
Instead, we continue to use the generic config, but generate the
correct set of lines as comments.

The system configuration you get with "-t none" works for smaller
files but fails for larger ones. This updates the generator to
produce a source file and linker script pair. (I kinda saw this
one coming -- it's why the gen/asm dialog has a combo box for the
file preview -- so it didn't require that much work.)
This currently generates a fixed script for a generic system with
64KiB of RAM, using .ORGs to set the addresses as before.
With this change, assembling a file with 65536 NOPs succeeds.
