Benedikt Meurer beebb2360f [cleanup] Cleanup JSArrayBuffer and TurboFan's handling of neutering. 
Cleanup the JSArrayBuffer bit fields to use the proper object macros
that are now otherwise used consistently across the code base. Also
change TurboFan to consistently bailout when it sees an array buffer
that was previously neutered, so that the generic path / builtins are
again the chokepoints for the spec violations (the fact that we don't
always raise exceptions when we see a neutered array buffer), except
for the ArrayBufferView accessor inlining in the JSCallReducer, where
we still turn the values into zero (because we don't have access to
a CALL_IC speculation guard in the common case).

This also removes the ArrayBufferWasNeutered simplified operator, and
does regular LoadField + Number bitwise operations instead, which is
good enough and allows us to get rid of a lot of unnecessary complexity.
