[demangler] Fix buffer growth
The output buffer growth algorithm had a few issues:
a) An off-by-one error in the initial size check, which uses
'>='. This error was safe, but could cause us to reallocate when there
was no need.
b) An inconsistency between the initial size check (>=) and the
post-doubling check (>). The latter was somewhat obscured by the
swapped operands.
c) There would be many reallocs with an initially-small buffer. Add a
little initialization hysteresis.
