// NOTES ON MANGLING:
// * Itanium spec says that Float80 encodes to "e" (like LongDouble), but the distinct lengths cause resolution problems.
// * Float128 is supposed to encode to "g", but I wanted it to mangle equal to LongDouble.
// * Mangling for non-standard complex types is by best guess
// * _FloatN is supposed to encode as "DF"N"_"; modified for same reason as above.
// * unused mangling identifiers:
//   - "z" ellipsis
//   - "Dd" IEEE 754r 64-bit decimal floating point (borrowed for _Float32x)
//   - "De" IEEE 754r 128-bit decimal floating point
//   - "Df" IEEE 754r 32-bit decimal floating point
//   - "Dh" IEEE 754r 16-bit decimal floating point (borrowed for _Float16)
//   - "DF"N"_" ISO/IEC TS 18661 N-bit binary floating point (_FloatN)
//   - "Di" char32_t
//   - "Ds" char16_t
