Original commit message:
The generator object methods "next", "send", and "throw" now
include some inline assembly to set up a resumed stack frame.  In some
common cases, we can just jump back into the frame to resume it.
Otherwise the resume code calls out to a runtime to fill in the operand
stack, rewind the handlers, and possibly to throw an exception.

Instead, create Local handles to pass them around. This also means that the
code needs to be shifted around a bit such that a handle scope exists when
creating threads.

Revert part of r14179. From the regression test's comment:

Currently, the gap resolver doesn't handle moves from a ConstantOperand to a
DoubleRegister, but these kind of moves appeared when HConstant::EmitAtUses
was changed to allow special double values (-0, NaN, hole). So we should
either enhance the gap resolver or make sure that such moves don't happen.
