Original commit message
[heap] Fix memory leak in the remembered set.
Empty slot set buckets can leak in the following scenarios.
Scenario 1 (large object space):
1) A large array is allocated in the large object space.
2) The array is filled with old->new references, which
allocates new slot set buckets.
3) The references are overwritten with smis or old space
pointers, which make the slots set buckets empty.
4) Garbage collection (scavenge or mark-compact) iterates the
slots set of the array and pre-frees the empty buckets.
5) Steps 2-4 repeated many times and leak arbitary many empty buckets.
The fix to free empty buckets for large object space in mark-compact.
Scenario 2 (no mark-compact):
1) A small array is allocated in the old space.
2) The array is filled with old->new references, which allocates new
slot set buckets.
3) The references are overwritten with smis or old space pointers,
which make the slots set buckets empty.
4) Scavenge iterates the slots set of the array and pre-frees the
empty buckets.
5) Steps 2-4 repeated many times and leak arbitary many empty buckets.
The fix to free empty buckets for swept pages in scavenger.

Original commit message:
Avoid disassembling Interpreted Regexp code
I found that v8 will crash when --print-code is turned on while Regexp
is interpreted. It crashes when trying to print Relocation info during
Disassembly. It should probably avoid printing out disassembly when the
Code object is a bytecode regexp.

[api] Add optional data pointer to GC callbacks
This can be useful when there may be multiple callbacks attached by
code that's not directly tied to a single isolate, e.g. working
on a per-context basis.
This also allows rephrasing the global non-isolate APIs in terms
of this new API, rather than working around it inside `src/heap`.

[d8] Bring PredictablePlatform in line with default platform
This removes a lot of special handling for the predictable platform.
Instead of executing spawned foreground and background tasks
immediately (i.e. inside the scope that spawns the tasks), just add
both to the foreground task queue.
This avoids existing special handling for predictable mode in wasm
async compilation, and should fix current failures on the predictable
bot.

d8: Make in process stack dumping optional
Adds a flag (--disable-in-process-stack-traces) to not install
signal handlers so that e.g. ASan signal handlers will work.
This flag mirrors chromium's one.

Original commit message:
[turbofan] Boost performance of Array.prototype.shift by 4x.
For small arrays, it's way faster to just move the elements instead of
doing the fairly complex and heavy-weight left-trimming. Crankshaft has
had this optimization for small arrays already; this CL more or less
ports this functionality to TurboFan, which yields a 4x speed-up when
using shift on small arrays (with up to 16 elements).
This should recover some of the regressions reported in the Node.js issues
https://github.com/nodejs/node/issues/12657
and discovered for the syncthrough module using
https://github.com/mcollina/syncthrough/blob/master/benchmarks/basic.js
as benchmark.

Original commit message:
This commit adds a getter for the private is_verbose_ member.
The use case for this comes from Node.js where the ability to avoid
calling FatalException if the TryCatch is verbose would be nice
to have.

VS2013 does not support defaulting move constructor and assignment
operator. This adds explicit definitions of those methods for two
classes.
This fix is required because we still support building addons with
VS2013 and the incompatibility is in v8.h.

es6/typedarray-construct-offset-not-smi allocates a 2G block of memory
and if there are multiple variants running at the same time this can
lead to crashes, OOM kills or the OS failing to allocate memory.
This patch limits us to running a single variant of the test.
