297b5d1074 fix [x]u65529 and above overflowing 
```

    _ = a;

        return (abiSizeAdvanced(ty, target, .eager) catch unreachable).scalar;
                               ^
```
This is only noticed in a debug build of zig and silently does the wrong
thing and overflows in release builds.

This happened to `[x]u65529` and above because of the ` + 7` on a `u16`.

Migrate mnemonic literals to tuples that represent the compressed

6c14eb2863 x86_64: optimize mir tag usage 
This moves all pseudo-instructions to a single `Mir.Inst.Tag` tag and
prepares to start coalescing similar mnemonics. 239 tags left in use.

bac3a28214 fmt: avoid canonicalizing enum fields named @"_" to _ 
This can be used to escape the usual meaning of `_` to indicate a
non-exhaustive enum and create an enum tag that is a literal underscore,
so zig fmt should allow this syntax.

Before, zig fmt changes

    const E = enum { @"_" };

to the semantically different

    const E = enum { _ };

After, it remains the same.
