[dmd-internals] Correction to name mangling doc

[Sean Kelly]

The current scheme just complicates demangling if the bool should be displayed as true/false instead of 1/0. I'd have to pull the actual element type out of the Hba and pass it in as an alternate type when parsing the integer value. Since the mangled name is the same length either way, it seemed like it might be a worthwhile convenience.

"i1" for "true", "i97" for "a", etc.  I'm inclined to say that the mangling should reflect the actual type of the values rather than using 'i' as a catch-all.  Does anyone disagree?  Combined with the fix for AA literals, I think the encoding should be:
