Currently `IsCurrentThreadReader()` can only be called outside
safepoint operations. We'll loosen that restriction for future CLs
which require calling this method inside safepoint operations.

This partially undoes changes from acbd51c08
because they are now known to increate RSS of AOT

This CL also removes length adjustment code from *String::InstanceSize
which tried to ensure that external string fits into a non-external

ClassLevel and Class.level have been unused for (at least) years.
This CL removes them.
Library.flags furthermore had the first bit unused after the 'external'

This CL shifts it down so the actual flags doesn't start at bit 1.

This adds a mechanism similar to that used in async functions where
exceptions are caught in the synthetic code and passed into the
generated body to be rethrow'n.
This ensures the exception is throw'n from the same place as the
original yield*, as per the spec.

The differences between the different implementations are very
minor, so abstract out the few that remain into Assembler:
* Change Load<X>FromPoolOffset to Load<X>FromPoolIndex and do pool
offset calculations internally, since all caller sites have the pool
index. (Especially important because the pool register is tagged on
X64 and ARM and untagged on ARM64, so this abstracts that away.)
* Add default for pool register argument on ARM, since ARM64 already had
one and X64 doesn't take a pool register argument.
Other changes:
* Use specific TestTypeABI registers within the helper method that adds
caller-side checks instead of passing registers as arguments and
document which registers are used for input or output (and when, if
they are used conditionally).

When loading a late field without initializer, we check if it was not
initialized and throw an exception. This change adds slow path (shared
if supported) for throwing LateInitializationError instead of calling
an initializer which would throw an exception. This improves register
allocation around accesses to such late fields.
In addition, this CL removes duplicated code for generating shared
stubs.

These checks are now performed in the dynamic closure call dispatcher.
To avoid having to create type argument vectors (TAVs) for default type
arguments at runtime, we cache a compile-time created TAV in the
ClosureData for the closure function which is retrieved by the
dispatcher when needed.
We also keep an associated packed field of information that can also be
determined at compile time:
* Whether the cached TAV needs instantiation or can share its
instantiator or function type arguments.
* The number of parent type parameters.
The former allows the generated IL to keep the invariant that the
InstantiateTypeArguments instruction (and the runtime entry it calls) is
only used for uninstantiated TAVs.
Also changes the destination name to an Value input for the
AssertSubtype instruction and adds handling for non-constant types and
names in that instruction's backend.
Additional changes:
* Adds new slots for ClosureData, Function, and TypeArguments.
* Adds a new kUnboxedUint8 representation (needed for
TypeParameterLayout::flags_, which is of type uint8_t).
* Extends LoadField to handle uint8_t unboxed native fields.
* Adds BoxUint8 for boxing unboxed uint8_t values.
