497487beec Consistently use a separate Lithium instruction for flooring division. 
Previously we tried to share some code on by a slightly confusing re-use
of LDivI for a (general) flooring division. Now we cleanly separate
concerns, just like for the rest of the division-like operations. Note
that ARM64 already did it this way.

If we really want to save some code, we can introduce some macro
assembler instructions and/or helper functions in the code generator in
a future CL, but we should really try to avoid being "clever" to save
just a few lines of trivial code. Effort != complexity. :-)

Renamed some related Lithium operands on the way for more consistency.

2) RUNTIME_HIDDEN: implemented in runtime, never called directly from JS builtins.
3) INLINE: inlined in both full and optimized code
4) INLINE_OPTIMIZED: inlined in optimized code, implemented in runtime for full code.

535f3427ca Pretenure call new support. 
When FLAG_pretenure_call_new is on, we emit mementos on new object creation
in full code, and consume the feedback in crankshaft. A key difference in the
generated code for stubs is the allocation of an additional type vector slot for the
CallNew AST node, which simplifies the CallConstructStub and CallFunctionStub
considerably.

Some performance tuning still needs to be addressed, therefore the flag is off at
this moment, though fully functional. The goal is to remove the flag as soon as
possible, which allows much code deletion (yay).

5e4febb06e Array constructor expects AllocationSite or undefined as feedback. 
Redefine Array constructor to expect an AllocationSite in the feedback
register or undefined. This will make code simpler as we support
pretenuring feedback for all constructed objects.

0acbcf9876 Reland "Add out-of-line constant pool support to Arm." 
This CL adds out-of-line constant pool support to Arm.  A ConstantPoolBuilder
object is introduced to manage building of the ConstantPoolArray for a given
code object.

This CL depends on the following CLs landing first:
