[demangler] Improve buffer hysteresis
Improve demangler buffer hysteresis. If we needed more than double
the buffer, the original code would allocate exactly the amount
needed, and thus consequently the next request would also realloc.
We're very unlikely to get into wanting more than double, after the
first allocation, as it would require the user to have used an
identifier larger than the hysteresis. With machine generated code
that's possible, but unlikely.
