ddf46ce8fd stmt_ins: refactor
The overall intent is to make writing a decompiler require less code
duplication.

"bits.hpp" and "stmt_enum.hpp" are replaced with "stmt_ins.hpp" which
is generated directly from dsp-notes.csv.

107eb18cd4 parser: allow immediate values that end with colon
This is funky syntax, but it doesn't hurt the accuracy of a parser.

Some people might prefer this to stylize references to labels.

118942521e test: add initial test makefile
This also adds support for "#" characters prior to immediates.

nop may also now appear in an op_t. The parser no longer generates nop_t--this
is instead now represented as an op_t with a zero-length ops vector.
