Without sound null safety result of int.parse is inferred as nullable,
making the IL test vm/dart/records_allocation_sinking_il_test dependent on
the sound null safety mode.
The test is changed so the argument 'x' of 'test' is always non-nullable
and always unboxed.

This is follow up to 65f4a733bb,
which switched optimized code to use fixed frame for outgoing
arguments.
Change Kernel to IL translation to handle null-checks in
invocations differently: this code used to duplicate receiver on
the stack to accomodate for PushArgument in unoptimized code, but
PushArgument has not been inserted since f4e61eacfd,
which means duplication of the receiver is no longer necessary.

We support allocating deeply immutable typed data in the Dart C API
already.
=> This CL adds a test for that.
Furthermore we hook into the already O(n) construction of
`List.unmodifiable(<list>)` and set the objects immutable bit
if all elements of `<list>` are also immutable.
=> This allows then sharing of such lists when sent across isolates.
We do this eagerly to
- avoid introducing complexity to the deep immutability check in
transitive copy algorithm
- avoids re-checking for the subgraph on every send (similar to
canonicalized bit for constants, we can simply rely on the
immutable bit)
If we ever optimized `List.unmodifiable()` (which always performs
runtime call atm) we could fold this checking into the place that copies
list elements from `<list>` to the newly allocated list.

The object graph copy code assumed kImmutableCid is used only for
list constants but it turns out our List.immutable([]) implementation
isn't using a wrapper-view, but instead a fixed-length immutable list as
with constants:
factory List.unmodifiable(Iterable elements) {
final result = new List<E>.from(elements, growable: false);
return makeFixedListUnmodifiable(result);
}
The list constants should already be handled via canonical bit.

When lowering patterns, front-end can add multiple distinct local
variables with the same name into the same local scope.
Previously, VM identified local variables in a local scope by name.
However, this no longer works with patterns.
With this change, local variables are now identified by pair (name,
kernel offset). Name is still taken into account as compiler can add
extra variables which do not correspond to kernel variables,
such as 'this'.

When building SSA form for callee graph during inlining, numbering of
SSA values starts with the number of SSA values in the caller graph.
However, parameter stubs may contain constants which are already added
to the callee graph and occupy certain range of SSA numbers. If that
number is larger than number of SSA values in the caller graph, then
numbers, already assigned to constants, can be incorrectly reused
during SSA construction.
The fix is to adjust number of SSA values in the callee graph
before parameter stubs are created, and then use current number of
SSA values as a starting point when building SSA.

Inlined functions might contain call-sites which can be devirtualized
in the context of the caller. To achieve that we add a pass which
calls canonicalization on all dynamic calls (and their data
dependencies) between rounds of inlining.
More specifically this helps cases which require interleaving
some redundancy elimination and inlining to remove the cost of
abstractions. The primary example is for-in loop with an array of
a known type which usually requires inlining `get:iterator` and
propagating iterable value through interator's fields to specialize
and inline `get:length` and `operator[]` on the `Iterable`.
See https://github.com/dart-lang/sdk/issues/48433 for example.

Our compiler shouldn't depend on current isolate, since it can
run on any isolate within an IG.
Doing this change, reveals two existing dependencies on current
isolate from compiler
- resolving native symbols in unoptimized compilations
- issuing of debug events for breakpoints
For the former we'll re-enter the currently active isolate that
triggered unoptimized compilation.
=> We may want to change that embedder API to not be based on
handles and instead give embedder a simple `const char*`.
For the ladder we'll enter the isolate corresponding to the
breakpoint debug event to be issued. We are at place where
all mutators are stopped, so that does seem okish.
=> Future could remove this by making Object Id Ring per-IG

int num_fields(16)
int field_names_index(kSmiBits-16)
where field names index is an index in the array available from
ObjectStore.
With the new representation of record shapes:
1) Size of record instances is reduced.
2) Number of comparisons for a shape test reduced from 2 to 1
(shape test is used during type checks).
3) A few operations removed from Record.hashCode.
4) Type testing stubs (TTS) are now supported for record types with
named fields. Previously it was not possible to check shape of records
with named fields in TTS as TTS cannot access object pool and cannot
load field names array).
