New issue 96 by nicolas.... at gmail.com: Using >> (bitShift:) instead of pow  
(raisedTo:)

By virtue of SLANG translation, interpreterAllocationReserveBytes uses  
pow((double)2,(double)n) to answer an int, wouldn't it better to just use a  
bit shift?

2^n <=> 1<<n, up to n=31
I doubt we reserve more than that, the result is signed anyway.

And this would remove yet another warning.
