6c8aed76ff [wasm] Check the size of a function body before storing it
We stored the size of a function body before we check that
these values are valid. This caused a failing DCHECK in the constructor
of WireBytesRef which checked for integer overflows. With this CL we
check the size of the function body before we create the WireBytesRef.

b9ee0657c6 [builtins] Unified C++ implementation of Map and Set iterators.
This is the first step in optimizing Map and Set iterators. This ports
all the base functionality including

 - Set.prototype.entries
 - Set.prototype.values
 - %SetPrototypeIterator%.next
 - Map.prototype.entries
 - Map.prototype.keys
 - Map.prototype.values
 - %MapPrototypeIterator%.next

to C++ and removes all the dead code and the previous half JavaScript
implementation. The next step is to port core parts to CodeStubAssembler
and finally inline the fast-paths into TurboFan directly. The relevant
design document is at:

  https://docs.google.com/document/d/13z1fvRVpe_oEroplXEEX0a3WK94fhXorHjcOMsDmR-8

Most of this work is very similar to how the Array iterator works and we
mostly follow the same process for the implementation.

124ff5322d [arm64] Clear the upper 32 bits after a TruncateDoubleToI
TruncateDoubleToI generated a 32-bit result but did not clear the upper
32 bits. This violated the invariant that the upper 32 bits should be
cleared when the result is 32 bits. This change fixes the bug mentioned
below. Clearing the upper 32 bits is also done on x64.

Remove all IsHeapObject/IsSmi checks from assembler and also from

Note for porters: In case it's unclear which macro-assembler
functions need to be modified, it may be best to wait until I
split MacroAssembler in a followup-CL, which will make that clear.

8e84b715b2 [arm] Introduce UseScratchRegisterScope
Introduce a stripped down version of UseScratchRegisterScope for ARM and use it
inside the assembler and macro-assembler. At the exception of the Call
instructions, we now use this scope instead of using the ip register
directly. This is inspired from how the ARM64 backend works.

In general, the benefit of doing this is we can catch cases where ip is being
used both by the caller and by the assembler. But more specifically, TurboFan
reserves r9 as an extra scratch register because ip can already be used by the
assembler. With this utility, we can isolate the cases in the code generator
which need an extra register and potentially fix them, allowing us to give r9
back to the register allocator.

This patch uncovered places in the assembler where we were using ip
unconditionally when we could have re-used the destination register instead.

a2fcdc7cc8 [runtime] Move profiler ticks from SFI to feedback vector
Instead of counting profiler ticks on the shared function info (which is
shared between native contexts), count them on the feedback vector
(which is not). This allows us to continue pushing optimization
decisions off the SFI, onto the feedback vector.

Note that a side-effect of this is that ICs don't have to walk the stack
to reset profiler ticks, as they can access the feedback vector directly
from their feedback nexus.

653f43d579 Revert of Set the current context to the function's context when entering to LAP. (patchset #14 id:540001 of https://codereview.chromium.org/2770003002/ )
Reason for revert:
Speculative: Seems to break webkit_unit_tests:
https://build.chromium.org/p/tryserver.v8/builders/v8_linux_blink_rel/builds/23247
https://build.chromium.org/p/client.v8.fyi/builders/V8-Blink%20Mac/builds/11038

Original issue's description:
> Set the current context to the function's context when entering to LAP.
>
> In case of LAP(lazy accessor pair), the function's creation context
> must be equal to the accessor holder's creation context, so this CL
> changes the current context to the accessor holder's creation context.

18e73287dc Set the current context to the function's context when entering to LAP.
In case of LAP(lazy accessor pair), the function's creation context
must be equal to the accessor holder's creation context, so this CL
changes the current context to the accessor holder's creation context.

ff3b948c6b [compiler-dispatcher] Move stepping logic to job
Instead of having the "next step" state machine logic in the compiler
dispatcher, move it to the compiler dispatcher job. This is a
prerequisite to having more generic jobs with slightly different state
sets, such as an optimizing compile job.
