The problem is that tagged slot could become a double slot after migrating of an object to another map with "shifted" fields (for example as a result of generalizing immutable data property to a data field).
This CL also adds useful machinery that helps triggering incremental write barriers.

CpuProfiler: simplify inlined function info magic.
I did some investigation and found that in the most cases
the old schema with the separate List for functions and inlines
gives us no memory benefits because more frequently we inlines
different functions into parent function. So the plain schema
wins a tens or even hundreds bytes a few thousand times.
The only drawback is that we will print the inlined body
the each time when we inline it. But is not a problem
because it happens only under FLAG_hydrogen_track_positions.
Also I added script_id to the structure, so it could be used later
by cpu-profiler.

Port
022ea7e05779f07b9327bcc2d4709fc80b2aeecb
Original commit message:
Provide an intrinsic %MathFloor / %_MathFloor that is used to optimize
both Math.ceil and Math.floor, and use the JS inlining mechanism to
inline Math.ceil into TurboFan code. Although we need to touch code
outside of TurboFan to make this work, this does not affect the way we
handle Math.ceil and/or Math.floor in CrankShaft, because for CrankShaft
the old-style builtin function id based inlining still kicks in first.
Once this solution is stabilized, we can use it for Math.floor as well.
And once that is settled, we can establish it as the unified way to
inline builtins, and get rid of the specialized builtin function id
based inlining at some point.
Note that "builtin" applies to basically every piece of internal
JavaScript/intrinsics based code, so this also applies to the yet to be
defined JavaScript based code stubs and handlers.

CpuProfiler: fix for CollectDeoptEvents test on arm64
We use slightly different schema for JumpTable on arm64 than for x64.
We do a branch (B) to the JumpTable from the code,
then a branch (B) to the end of jump table code
and then branch to the deoptimizer code with putting
the return address into lr register (Call which is actually Blr).
As a result the 'from' address in Deoptimizer always points to
the end of JumpTable code and we can get nothing from this information.
0) I moved save_doubles and needs_frame code out of for_loop.
1) I replaced B commands with Bl so we put different return addresses
to lr register for the different jump table entries and replaced
the final Call with Br which do not touch lr register.
Also I removed the last_entry check so we will always do the Bl
even for the last entry because we need the right address in lr.
I don't think that this will affect the performance because it
just one more branch for entire deopt mechanics.
