4e08810278 Finish removal of "disable label localizer" feature
The label localizer is now always on.  The regression tests turned
it off by default, but that's no longer allowed, so the generated
output has changed for many of them.  The tests themselves were not
altered.

835c1c7fe2 Reverse position on '#' in block move operands
During a discussion with the cc65 developers, I became convinced that
generating "MVN $01,$02" is wrong, and "MVN #$01,#$02" is correct.
64tass, cc65, and Merlin 32 all accept this syntax; only ACME does
not.  Operands without a leading '#' should be treated as 24-bit
values, and have the bank byte extracted.

This change updates the on-screen display and assembled output to
include the '#'.  The ACME generator uses a Quirk to suppress the
hash mark.  (It doesn't currently accept values larger than 8 bits,
so there's no ambiguity.)

98914e9f80 Treat BRK as a 1-byte instruction
The 65816 definition makes it a two-byte instruction, like COP.  On
the 6502 it acted like a two-byte instruction, but in practice very
few assemblers treat it that way.  Very few humans, for that matter.
So it's now treated as a single byte instruction, with the following
byte encoded as a data value.

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.
