Initial implementation for concurrent shared arrays. Current implementation exposes a `SharedArray` constructor, but its syntax might
change in the future.

Shared arrays can be shared across Isolates, have a fixed size, have no
prototype, have no constructor, and can only store primitives, shared structs and other shared arrays. With this CL shared structs are also allowed to store shared arrays.

The Backing storage for the SharedArrays is a `FixedArrayBase`. This CL introdces a new ElementKind: `SHARED_ARRAY_ELEMENTS`. The new kind should match the overall functionality of the `PACKED_SEALED_ELEMENTS` kind, but having it as standalone kind allows for easier branching in CSA and turbofan code.

Instead of doing multiple separate checks with branches, turn the

This means that the symbols and strings for properties than can

  - created a AugmentedOptions class to take care of non trivial option look-ups
  - moved some calculation closer the the actual data
- promoted parameter that was passed around a lot (options) to filed in the offending class
- similar object creation looks a bit more similar
- CommandContext provides a wrapper that ensures resource de-allocation
- separate tests from standard and num_fuzz runners
- added a couple of more tests to improve coverage

This is still in flux. But further changes risk creating a disconnect between the original implementation and further refactorings.

roll_merge.py manually checks out V8 into a temporary directory, locally
builds a cherrypick, and uploads this to Gerrit. However, Gerrit has its
own REST API which allows cherrypicking. Using this API directly has two
advantages:

  1) We don't need to perform any local checkouts, so it's much faster,
     and
  2) The cherry-picked commit is marked as a cherry-pick by Gerrit,
     which means Rubber-Stamper-Bot will treat it as a cherry-pick.

The implementation for now is very simple, and doesn't support things
like cherry-picking multiple revisions or applying an additional local
patch. It does, however, increment the patch value in v8-version.h, and
tries to set Owners-Override +1.

The last line of output (which is not terminated by a newline) was not

reading user input. The latter seems more future-proof.

The test cctest/test-v8windbg recently started failing because the
v8windbg debugger extension is unable to read the "flags" field on a
SharedFunctionInfo instance. This occurs because one of the bitfields
within "flags" has type OSRCodeCacheStateOfSFI, which is only declared
using an "opaque enum declaration":

  enum OSRCodeCacheStateOfSFI : uint8_t;

When WinDbg fails in its attempt to look up that type, v8windbg responds
by failing to construct anything at all for "flags". However, the other
17 bitfields in "flags" can be represented successfully, so a more
useful behavior is to just skip the one failed entry.

Split off a TurbofanFrame from OptimizedFrame, and make MaglevFrame a
subclass of OptimizedFrame. This allows it to be treated as an optimized
frame by code that is looking at deoptimization data.
