This CL fix an assertion inside Serializer::WriteInstructions
that was always failing in debug mode AOT 32-bit platforms
which used to happen when Utils::IsUint was called with a
signed type value was being passed.
It also fixes a bug that happens on some architectures that do not
support atomic unaligned load operations of 64-bit values.

Non-nullable floating point fields (double, Float32x4, Float64x2)
are fully unboxed in their classes.
A bitmap for each class was added to the shared class table in order to keep
track of the pointers of the classes. Since all classes in Flutter Gallery
have less than 64 fields, the bitmap is represented by a 64 bit integer and
fields whose offset is more than 64 words are not unboxed.
The instance sizes and field offsets might change between target and host
in cross-compilation, since the number of words used to store unboxed fields
may differ.

This work pulls in v8 support for these features with
appropriate changes for Dart and closes
https://github.com/dart-lang/sdk/issues/34935.
This adds support for the following features:
* Interpreting patterns as Unicode patterns instead of
BMP patterns
* the dotAll flag (`/s`) for changing the behavior
of '.' to also match line terminators
* Escapes for character classes described by Unicode
property groups (e.g., \p{Greek} to match all Greek
characters, or \P{Greek} for all non-Greek characters).
The following TC39 proposals describe some of the added features:
* https://github.com/tc39/proposal-regexp-dotall-flag
* https://github.com/tc39/proposal-regexp-unicode-property-escapes
These additional changes are included:
* Extends named capture group names to include the full
range of identifier characters supported by ECMAScript,
not just ASCII.
* Changing the RegExp interface to return RegExpMatch
objects, not Match objects, so that downcasting is
not necessary to use named capture groups from Dart
**Note**: The changes to the RegExp interface are a
breaking change for implementers of the RegExp interface.
Current users of the RegExp interface (i.e., code using Dart
RegExp objects) will not be affected.

Since the kernel reading helpers have been extended to not only work
with a kernel blob in C heap, but also work based on a [TypedData]
buffer in the VM heap, access to the [TypedData] buffer is on the hot
path now.
This hot path is slowing things down considerably, in particular due
to NoSafepoingScope's.
This CL removes a critical NoSafepoingScope when accessing the
[TypedData] in read-only mode. It also allows passing in the [Thread]
directly, to avoid TLS lookups.

This CL corrects handling of overflows in range analysis to
account for wrap-around (which happens with new integer semantics).
* If there is an overflow while doing computations in range
analysis, the resulting range is approximated as full int64 range.
* For symbolic range boundaries 'symbol + offset', offset is checked
to stay within [kMinInt64 - kSmiMin, kMaxInt64 - kSmiMax] in order
to guarantee that overflow doesn't occur.

This reverts commit f13f772bb2.
Reason for revert: dartk(p)-strong debug mode is completely broken
because we convert int values non-representable as Smi to Smi, which
triggers that assert. The code that does tagging checks that
Untag(Tag(x)) == x, however for our purposes this identity does not
need to hold because we only care about lower bits and ignore the sign.
Reverting to restore green-ness of DEBUG builds.

This changeset revises --limit-ints-to-64-bits option to
change range of integers from unlimited to int64.
On overflow, integer arithmetic operations silently wrap around and
discard extra bits. No Bigints are allocated in case of overflow.
This changeset is the 1st part in the series of changes, it revises the implementation of integer arithmetic operations. More changes will follow.

Like HOST_ARCH_*, HOST_OS_* describes the OS the VM is running on, which may be different from the OS the VM is generating code for during AOT compilation.
Currently we conflate the two when emitting AOT as assembly, and we get away with it because Flutter only uses assembly for targeting iOS and one can only target iOS from a Mac, but we expect to use assembly for Android as well so native tools can unwind Dart frames.

- Add the "isolate" command which allows the user to switch isolate by name or number. Supports completion.
- Add the "isolate name" command which allows the user to rename an isolate. Add the "setName" method to the service protocol to support this. Isolates now have a debugger_name() in the vm.
- The new IsolateUpdate event notifies the client when an isolate name changes.
- When an isolate is updated, update the page's isolate too, so the navbar is accurate.
- Update isolate summary to display isolate number.
- Rework how the isolate's name is computed because we were getting garbagey names in the IsolateStart event (SpawnState was not yet set).
- Make sure that the debugger doesn't subscribe to events multiple times.
- "info isolates" is now "isolate list".
- Rework reporting of vm and isolate startTime in the service protocol and in Observatory.
- Fix bug in command completion when subcommands and other completions share common prefixes.
- Rework isolate accounting in the VM object in Observatory. We now create Isolates in getFromMap rather than from IsolateStart events, per se. Rewrite the isolate updating code.
- IsolateStart and IsolateExit events are now owned by the Isolate itself, rather than the vm.
- Return the actual result in pause/resume/etc.
- Add assertion in JSONStream::PrintProperty64 that the result fits in a javascript double. Sigh.
- Stop sending GC events for the service isolate. Add assertions to guard against this happening in the future.
- Misc improvements in error reporting.
