478afa542e Fix 64tass code gen corner case
On the 65816, if you say "JSR foo" from bank $12, but "foo" is an
address in bank 0, most assemblers will conclude that you're forming
a 16-bit argument with a 16-bit address and assemble happily.  64tass
halts with an error.  Up until v1.55 or so, you could fake it out
by supplying a large offset.

This no longer works.  The preferred way to say "no really I mean to
do this" is to append ",k" to the operand.  We now do that as needed.

I didn't want to define a new ExpressionMode for 64tass just to
support an operand modifier that should probably never actually get
generated (you can't call across banks with JSR!), so this is
implemented with a quirk and an op flag.

64tass v1.56.2625 is now the default.

8fc38d5d90 Update ACME version in docs
Added v0.97 to list of successfully-tested versions.

Noted that regression tests are now run against v0.97.

67c713ea7d Change some words
Replace "hint" in a few more places.  Mention W65C02 in main README.
State that new PRG feature is only enabled for 64tass.

34ba47e71d Add W65C02S support, part 3
Modified the asm source generators and on-screen display to show the
DP arg for BBR/BBS as hex.  The instructions are otherwise treated
as relative branches, e.g. the DP arg doesn't get factored into the
cross-reference table.

ACME/cc65 put the bit number in the mnemonic, 64tass wants it to be
in the first argument, and Merlin32 wants nothing to do with any of
this because it's incompatible with the 65816.

Added an "all ops" test for W65C02.

3ff0fbae34 Regression test rework, part 1
The regression tests were written with the assumption that all cross
assemblers would support 6502, 65C02, and 65816 code.  There are a
few that support 65816 partially (e.g. ACME) or not at all.  To best
support these, we need to split some of the tests into pieces, so
that important 6502 tests aren't skipped simply because parts of the
test also exercise 65816 code.

The first step is to change the regression test naming scheme.  The
old system used 1xxx for tests without project files, and 2xxx for
tests with project files.  The new system uses 1xxxN / 2xxxN, where
N indicates the CPU type: 0 for 6502, 1 for 65C02, and 2 for 65816.
For the 1xxxN tests the new value determines which CPU is used,
which allows us to move the "allops" 6502/65C02 tests into the
no-project category.  For 2xxxN it just allows the 6502 and 65816
versions to have the same base name and number.

This change updates the first batch of tests.  It involves minor
changes to the test harness and a whole bunch of renaming.

df04de61e6 Improve visualization
Various improvements:
- Switched to ReadOnlyDictionary in Visualization to make it clear
  that the parameter dictionary should not be modified.
- Added a warning to the Visualization Set editor that appears when
  there are no plugins that implement a visualizer.
- Make sure an item is selected in the set editor after edit/remove.
- Replaced the checkerboard background with one that's a little bit
  more grey, so it's more distinct from white pixel data.
- Added a new Apple II hi-res color converter whose output more
  closely matches KEGS and AppleWin RGB.
- Added VisHiRes.cs to some Apple II system definitions.
- Added some test bitmaps for Apple II hi-res to the test directory.
  (These are not part of an automated test.)

8d0ce87ec7 Experiment on uncategorized data analysis
Tried something to speed it up.  Didn't help.  Cleaned up the code
a bit though.
