2f74fce80b Expand set of things that work with double-click on opcode
If you double-click on the opcode of "JSR label", the code view
selection jumps to the label.  This now works for partial operands,
e.g. "LDA #<label".

Some changes to the find-label-offset code affected the cc65 "is it
a forward reference to a direct-page label" logic.  The regression
test now correctly identifies an instruction that refers to itself
as not being a forward reference.

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.

a8af7e8794 Improve the "common" expression formatter
To avoid confusing the assembler, expressions with a leading
parenthesis like "(foo & $ffff) + 1" are prefixed with a "0+".  This
is not necessary if the operand begins with a '#'.

61914c8f79 Progress toward 64tass expression support
Gave cc65 its own expression generator, as the precedence table seems
atypical if not unique.  Configured 64tass to use the "simple"
expression mode.

Added some operations on a 32-bit constant to 2007-labels-and-symbols
to exercise the current worst-case expression (shift + AND + add).
Tweaked the Merlin expression generator to handle it.

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 '_'.

96ee33ae8c Optionally add spaces in the "bytes" column
Affects the display list and copy/paste text.  Makes the column
three spaces wider, but makes it easier to read.

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.
