Remap labels that use opcode mnemonics In a recent survey, three out of four cross assemblers surveyed recommended not using opcode mnemonics to their patients who use labels. We now remap labels like "AND" and "jmp", using the label map that's part of the label localizer. We skip the step for Merlin 32, which is perfectly happy to assemble "JMP JMP JMP". Also, fixed a bug in MaskLeadingUnderscores that could hang the source generator thread.

Attempt to generate segment names for cc65 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. (issue #39)

Label rework, part 5 Implemented assembly source generation of non-unique local labels. The new 2023-non-unique-labels test exercises various edge cases (though we're still missing local variable interaction). The format of uniquified labels changed slightly, so the expected output of 2012-label-localizer needed to be updated. This changes the "no opcode mnemonics" and "mask leading underscores" functions into integrated parts of the label localization process.
