This allows the JSIntrinsicLowering to optimize the cloning of literal
boilerplate objects using either the FastCloneShallowArrayStub or the
FastCloneShallowObjectStub when applicable.

Currently, this doesn't really help to generate better code,
nevertheless this is the right thing to do. When our type system(s)
are fixed, this should avoid falling back to floating point operations
in various cases.

Currently this only sets branch hints, so we get unlikely code "out of
the way", but in the long run the register allocator needs some love
to treat the unlikely code as, well, unlikely. :-)

This adds support for the double bits intrinsics to TurboFan, and is
a first step towards fast Math functions inlined into TurboFan code
or even compiled by themselves with TurboFan.
