In r243819, the individual size of an audio channel was limited to 2^30
float samples, however an AudioBuffer can be made to have a high number
of channels.
The webaudio/AudioBuffer/huge-buffer.html test attempts to allocate an
AudioBuffer made of 32 channels with 2^30 float samples, this would require 2^37 bytes.
We limit the total size of an AudioBuffer to 2^32 float samples (2^34 bytes).
