This reverts commit d79787771e.
Reason for revert:
This caused significant performance regressions on our protobuf_decode* benchmarks (probably on more benchmarks, but we don't yet have results due to some perf infra issue).
To avoid letting the regressions land for downstream users we'll revert it.
We should measure performance impact before landing this again.

Based on the unified typed data layout, we can now inline accesses to
typed data interface classes if there are no 3rd party implementations
of those interfaces.
Example: If a receiver is of type Uint8List and we call `[]` or `[]=` we
will inline the byte access.
Instead of changing the existing inliner / call specializer we add this
as an extra pass: If the inliner / call specializer infer that the
receiver type is e.g. internal typed data then it will perform the
inlining itself using more optimized LoadIndexed instruction.
=> Only if those existing optimization passes have not been able to inline
the access will we, later on in the compilation pipeline, run a
specialized pass which will inline the accesses using LoadUntagged +
LoadIndexed (which is slightly less efficient than using only LoadIndexed
for internal typed data).
As a first step this is only done for AOT.
For ease of writing tests matching certain IR graphs this CL also adds a
IR pattern matcher.

In general we would like to keep previous results of type propagation passes, however this
leads to situations where CompileType objects owned by definitions are cached as reaching
types at uses that are no longer directly connected to the definition itself.
This leads to situations when type propagator updates the type of the definition in place
via Definition::UpdateType, but does not enqueue an instruction which uses this type which
leads to incorrect fix-point computation.
As a fix we make the fact that some CompileType objects are owned by definitions explicit
by assigning [CompileType::owner_] field. Whenever we encounter situation that reaching type's
owner does not match current definition flowing into use we clone compile type to disconnect
it from original owner and prevent hidden mutation.
This CL also fixes two minor issues:
- incorrect computation of non-nullable type from a nullable CompileType with a cid;
- assings CompileType to LoadIndexedUnsafe instructions emitted by prologue builder;

Rationale:
The "unoptimized code" representation is really a stack
machine that pushes and pops arguments. The intermediate
representation did not show the correct labeling for
"temporaries", in particular around push arguments.
This CL fixes that bug, making the human readable form

it allows for proper stack depth computations.

Sharpen condition on OSR points a bit.

This moves the length field as well as an inner pointer to the start of
the data into the RawTypedDataBase class. The inner pointer is updated
on allocation, scavenges and old space compactions.
To avoid writing more assembly the typed data view factory constructors
will be generated using IL, which will update the inner pointer. This
required adding new IR instructions and changing the existing
UnboxedIntConverter instruction.
This is the foundation work to de-virtualize calls on the public typed
data types, e.g. Uint8List.

Parameter instructions inside CatchBlockEntry's initial definitions
are similar to Phi instructions: Parameter value at entry to the
catch would be taken from corresponding slot in the environment
attached to the instruction which threw the exception which is
being caught.
Thus similarly to Phi-s Parameter instructions can be redundant (if they
always evaluate to the same value - no matter where control arrives
from) or dead (if their value never reaches real instruction).
We already had an analysis to discover subset of redundant Parameter-s
which always evaluate to a constant value.
This CL introduces analysis to eliminate dead Parameter-s.
