Flutter uses the same clang toolchain as Fuchsia. This CL puts Dart
on that toolchain, as well. This roll should entail no changes to
glibc version requirements on Linux.
The Fuchsia buildtools distribute clang-format with the toolchain
rather than separately, so this CL introduces forwarding scripts
that are copied to the right place under //buildtools.
This CL sets the default for the number of workers in //tools/gn.py
to 1, as the newer GN version fails occasionally when run
concurrently with other invocations.
As Flutter does, this CL uses the clang toolchain to build for
Android. Thus, it is now possible to build for Android on MacOS.
This change is a prerequisite for assembling the SDK in GN
rather than with a python script:

and will be nicer for making prebuilt SDKs for Fuchsia.

The canonical name table is copied into a typed data array in the VM's
heap. The encoding is the same as in the binary except that the
integer indexes are fixed-size.
Canonical names are now integer indexes instead of objects allocated
in the C++ heap.

Some of the factories methods don't accept yet enough tokens, and fileOffset(s) for them are set externally.
Also PropertyGet, SuperPropertySet, MethodInvocation which are used in accessors, are not converted yet.

The assertions which tried to assert that we only use
StackFrameIterator to walk frames of the current thread was incorrect.
We already have cases where other threads will walk the stack of the
mutator thread, see below for an example where this can happen.
Thread::VisitObjectPointers was incorrectly passing Thread::Current() to
the StackFrameIterator instead of 'this'. (Code in thread_registry.cc will
loop over a number of threads and calls VisitObjectPointers on them)

This is mainly so that all of the code relating to test.dart is in one
directory tree so things like "Find All Usages" work a little better.
It felt weird to me to have a .dart file two directories up importing a
bunch of stuff within "testing/dart/".
Also cleaned up the affected code since it could use a little love. I'm
working on getting test.dart running DDC tests, but from poking around,
it seems like it could use some housekeeping as well.

Copy the Kernel string offsets into a uint32 array in the VM's heap.
This avoids allocating small string objects with new and avoids having
a table of the canonical strings.
Instead of an offset and a size, strings are now represented as
indexes into the string table in the heap. The start offset of string
N is found at byte offset N*4 because it is a uint32, and the end
offset is found at byte offset (N+1)*4. The strings themselves are
just integer indexes instead of pointers.
In the stream flow graph builder, string access is all random access.
