    pan/va: Add Valhall assembler · abb7f827

    This Python script acts as a standalone assembler. It takes Valhall
    instructions with Mesa-flavour syntax, parses them, errors out if there
    are syntax errors, and writes out an assembled binary if there are not.
    It also is available as a programmatic interface for automated testing.
    While this attempts to handle syntax errors, it does not check
    semantics. It will happily compile programs that fault, provided each
    instruction locally 'looks' plausible.
    The code itself is quite small, despite supporting most of the known
    ISA, because the syntax is regular and the heavylifting is done by
    ISA.xml and
