The operand size is dropped from Address/FieldAddress constructors on
arm64. This makes code using Address/FieldAddress less fragile, avoids
repeating size both in the Address/FieldAddress and load/store
instructions, and better aligns arm64 Address/FieldAddress with other
architectures.

On arm64 Address can assume certain load/store size depending on the
value (alignment) of the offset. This may cause assertion failure
"runtime/vm/compiler/assembler/assembler_arm64.h: 2750: error: expected: a.log2sz_ == -1 || a.log2sz_ == size".
This change fixes build on arm64c in debug mode by using an unaligned
offset. This is a follow-up to https://dart-review.googlesource.com/c/sdk/+/259920.

Instead apply the same approach as we do in AOT: unbox based on the
static type information. There are no TFA results available in JIT,
but we could still unbox fields when running in sound null-safety.

* Merge ClassTable and SharedClassTable back together;
* Simplify handling of multiple arrays growing in sync;
* Refactor how reload deals with ClassTable.
The last change is the most important because it makes it
much easier to reason about the code. We move away from
copying bits and pieces of the class table and shared
class table into reload contexts.
Having two class table fields in the isolate group makes
it easier to reason about. One field contains program
class table (one modified by kernel loader and accessed
by various program structure cid lookups) and heap
walk class table (used by GC visitors). Normally these
two fields point to the same class table, but during
hot reload we temporary split them apart: original
class table is kept as a heap walk class table, while
program class table is replaced by a clone and updated
by reload.
If reload succeeds we drop original class table and
set program class table as heap walk one.
If reload fails we drop the program class table and
restore original one from heap walk table.

In order to compute type, ParameterInstr::ComputeType() uses
environment index to get a LocalVariable from LocalScope,
assuming that environment index matches a variable index in the scope.
This is only true for direct parameters (which are not copied in
prologue).
This change limits use of LocalVariable type for ParameterInstr
corresponding to direct parameters. Note that it only affects
Parameter instructions used in catch block entries, as
ParameterInstr in function entry always corresponds to a direct

This is a reland of commit b8d4e24338
How the failures were fixed:
1. My ExternalSizeLimit test crashed on msvc because I was using a
0-sized array. I have now changed that array to have size 1.
2. My ExternalSizeLimit test crashed on x64c because
ExternalTypedData::MaxElements(kExternalTypedDataUint8ArrayCid) is much
smaller than kMaxAddrSpaceMB/4 on x64c. I now call
ExternalTypedData::New() with a length argument of 1, and just pretend
that the external allocations are larger when calling
FinalizablePersistentHandle::New().
