Introduce a new AnyToBoolean simplified operator to handle the later
lowering of boolean conversions. Previously we tried to hack that with
the generic JSToBoolean, having its context set to zero, but that lead
to various problems/bugs and did not handle all cases.

We cannot just clear the result register optimistically, because the
register allocator might assign the same register to result and buffer.

Change InstructionOperand to use a 64-bit field for encoding the operand
information instead of the 32-bit field that was used before. Ideally we
wouldn't use the Zone-allocated bit field at all, and use an integer
instead of the pointer; but that requires fixing the register allocator
first, which will take some time.

Using the optional parameter, Blink can tell V8 whether the disposed
frame was a main frame. In that case, we might want to reset GC

The CommonOperatorReducer currently takes care of redundant Phis,
EffectPhis and Selects. This functionality overlaps with ControlReducer,
but is required to make certain optimizations effective, since the
ControlReducer only runs really early and really late in the pipeline
and therefore other reducers aren't reapplied properly after redundant
phi/select elimination.

The test driver doesn't know at the moment if optdebug 1 or 2 has been used (the first is used on the bots, the second
locally in quickcheck). It can't know therefore if slow
asserts can be enabled or not. Trying to enable them leads
to a warning if they weren't compiled, which causes webkit
1:1 text comparison to fail.
