* Use the current tear-off syntax for constuctors in the example
* Add references to the code where certain maps are defined.

This is a reland of commit 43ce5487c1
In addition to removing type check, switch range checks are adjusted
in order to avoid call to 'int.operator<=', which can be removed by
tree shaker in AOT/product mode, causing NoSuchMethodError at runtime.

The scope of the lock is coarsened from per-element to per-page. This effectively causes the concurrent sweeper to pause during a scavenge in the case the sweeper encounters empty pages, preventing the sweeper from performing munmap during the scavenge.

Fixing direct uses of the deprecated `Identifier get name` is apparently
only about a half of the work. I should have followed my own advice to
the clients and prepared better.
These changes are necessary because we will stop creating and
visiting `Identifier`, and so `NamedType` should be handled directly.

This allows users of Visual Studio Code to open the sdk/ directory.
Without this, attempting to open the root of the repository results

The bug is that the disassembler doesn't do any bounds checking, other
than the outer while loop in Disassembler::Disassemble. For multi byte
instructions it relies on having well-formed input to avoid OOB errors.
This test is testing something that doesn't happen in real disassembly,
because usually the invalid machine code is embedded in valid machine
code, so there would be plenty of buffer between the invalid section
and the end of the input. The ideal fix would be to rewrite the
disassembler to do bounds checks, but short of that we can just add
some buffer to the end of bad_input.

The ffi-callback related information on the [Thread] object is metadata
corresponding to ffi-callback-trampoline [Function] objects. There is
nothing thread or isolate specific about it.
Moving it away from [Thread] is needed because an [Isolate] can
have different [Thread] objects across its lifetime (see [0]): When
the stack of an isolate is empty, we reserve now the right to
re-cycle the [Thread]. If the isolate later runs again, it may
get a new [Thread] object.
This CL moves this information from [Thread] to the [ObjectStore]. In
addition we make the compiler be responsible for populating this
metadata - instead of doing this per-call site of
`Pointer.fromFunction()`. It will be preserved across snapshot writing
& snapshot reading (for AppJIT as well as AppAOT).
Similarly the JIT trampolines that are on Isolate aren't isolate
specific and can go to [IsolateGroup]. This simplifies doing the above
as the compiler can allocate those as well.
The effect is that [Thread] object gets smaller, GC doesn't have to
visit the 2 slots per-thread. It comes at expense of 2 more loads
when invoking the callback.
