It avoids strange performance behavior where hot functions do not
get optimized if there is no GC to promote them, and it does not seem
to hurt us otherwise.

On IA32 we use InstanceofStub::left(), but on x64 we have just used rax and rdx directly. This fixes the assertion crashes on x64 crankshaft.

This change makes the full code generator always materialize smi constants to match the behavior
 of the environment tracked in the optimizing compiler. The mismatch between environment
and what the non-optimized code causes problems and potentially crashes when doing deoptimization
and OSR.

When deoptimizing from the key subexpression of a keyed arguments access,
the unoptimized code expects to find the value of the receiver on the
expression stack.  The environment of the optimizing compiler did not
contain this value during evaluation of the key subexpression.

The current version includes an extra jump compared to IA32, because
we need to load the jump address into a register and do an indirect
jump, but in the normal case we just jump over this by negating the
deoptimization conditional.
