a88c746419 Work around cc65 single-pass behavior
The cc65 assembler runs in a single pass, which means forward
address references default to 16 bits.  For zero-page references
we have to add an explicit width disambiguator.  (This is an
unusual situation that only occurs if you have a zero-page .ORG
in the file after code that references it.)

With this change, 2014-label-dp passes, and no other regression
tests were affected.

c80be07f73 Work around Merlin 32 instruction parsing bug
The 2014-label-dp test now passes.  Prior regression tests are
unaffected.

Also, renamed an IGenerator interface to more accurately reflect
its role.

f7e5cf2f45 Progress toward 64tass support
Most tests pass, but 2007-labels-and-symbols fails because the
expressions recognized by 64tass don't match up with either of the
other assemblers.

This is currently using a workaround for the local label syntax.
64tass uses '_' as the prefix, which is unfortunate since SourceGen
explicitly allowed underscores in labels.  (So does 64tass for that
matter, but it treats labels specially when the '_' comes first.)
We will need to rename any non-local user labels that start with '_'.

ab9287fef8 Progress toward new assembler configuration
Changed the "quick config" buttons for the asm config and pseudo-op
tabs into a drop-list and "set" button.  The default values for
each assembler are now defined in the Asm*.cs file, rather than in
the settings code.
