Improve code for integral modulus calculation.
Depending on what we know about the right operand, we basically do 3
different things (and the code is actually structured this way):
* If we statically know that the right operand is a power of 2, we do
some bit fiddling instead of doing a "real" modulus calculation.
This should actually be done on the Hydrogen level, not on the
Lithium level, but this will be a separate CL.
* If type feedback tells us that the right operand is a power of 2, we
do the same as above, but guarded by conditional deoptimization to
make sure that the assumption is still valid. In the long run, we
should make this guard visible on the Hydrogen level to make it
visible for GVN and other optimizations.
* In the general case we only do the minimum steps necessary and don't
try to be too clever, because cleverness actually slows us down on
real-world code.
If we look at the code gerators for LModI, we actually see that we
basically have 3 (4 on ARM) fundamentally different translations. I
don't really like lumping them together, they should probably be
different Lithium instructions. For the time being, I restructured the
generators to make this crystal-clear, at the cost of some duplication
regarding the power-of-2 cases. This will go away when we do the
strength reduction on the Hydrogen level, so I'd like to keep it as it
is for now.
Note that the MIPS part was only slightly restructured, there is still
some work to do there.

Allocation type info advice consumed in bailout path leads to assert failure.
If the runtime is taken for a constructor like "new Array(100000)", where
allocation site info already led to an elements kind of DOUBLE, then the runtime
would fail to transition the array to dictionary mode. Better to recognize this
case and avoid wasting time by following the advice. Furthermore, it offers a
way to recognize that the array should be in dictionary mode (though a future
checkin will capitalize on that).

MIPS: Turn off allocation site info for crankshafted array constructor calls.
Port r14934 (dbddd7e)
Original commit message:
Once we crankshaft a method, we should turn off allocation site info for
constructed arrays. Additionally, the semantics for doing this were
awkward because the constructed array code stubs get an
AllocationSiteMode as a minor key, but it's used as a permission to
determine the final mode locally based on ElementsKind. I refactored
this to a simpler boolean for override or local control.

MIPS: Deprecate FACTORY helper macro.
Port r14931 (a914442)
Original commit message:
This removes the FACTORY helper macro to avoid accidental TLS access
when using the factory. Most internal code has access to the Isolate by
now whereas tests which are not performance critical still heavily use
TLS access through explicit Isolate::Current() calls.

Prevent excessive processing of weak maps while marking.
This makes sure processing of Harmony weak maps is only triggerd twice
during a mark-compact collection. Note that the processing itself still
is a fix-point iteration with quadratic worst-case time.
