This test verifies stack traces of certain type errors.
In AOT mode, stack traces only contain line numbers but not columns.
So, the test is updated to accomodate for AOT stack traces.
Also, the test is skipped in 'dwarf' and 'obfuscated' modes as
they don't provide symbolic stack traces.

Mark tests that contain errors about using a class as a mixin to use
language version 2.19 where that's not an error.
This may not fix all of the tests because it's the language version of
the library where the class is declared that matters, not where the
class is used as a mixin. But most tests have all of their declarations
in the same library, so this should fix most.

This CL changes the IL building for reachability fences to their call
sites. This enables us to catch the field load and tell it to not emit
an initialization check for late fields.
The sentinel value will now flow into the ReachabilityFenceInstr, where
it will be discarded.

Deprecates the class and makes it implement `Error` (more specifically
`UnsupportedError`).
Code throwing `IntegerDivisionByZeroException` should be migrated to
throwing `unsupportedError` directly, code catching the exception class
should start catching `UnsupportedError` immediately (or reconsider why
they are catching at all).
Integer division by zero also covers other ways that a double division
can give a non-number result (any infinity or NaN result of the division prior to calling `truncate()` on the result, will cause `~/` to throw).

Field::RecordStore inspects the object being pointed to. However,
it is not guaranteed that that objects has been initialized in
*DeserializationCluster::ReadEdges, that depends on the order of the
clusters.
In the reproduction, the TypedDataView cluster comes after the cluster
containing the instance. This leads to doing a field store while the
length field of the TypedDataView has not been read yet and is 0. This
causes a Field::RecordStore with value 0, which subsequently gets used
in compilation causing RangeErrors.
This CL delays the Field::RecordStore from ReadEdges to PostLoad so that
all objects are initialized before they are inspected by RecordStore.

When we detect that a temporary variable is being reused
with a different type, we change the type of the temp
to dynamic.
This allows us to retain types for any non-reused temps.
For any dynamic temps we still have type information available
for use sites, which we can pass on via unsafeCast.
One drawback of this approach is that we don't know ahead
of time which temps are reused, and get turned into dynamic,
so we have to unsafeCast all uses.
This change is similar to what was done in:

Before value is stored into Float32List, it is converted to 32-bit
float using DoubleToFloat instruction. If allocation sinking
eliminated the allocation of Float32List but we need to deoptimize,
the list is materialized and elements are filled. In such case,
we shouldn't perform double->float conversion as it already happened.
This change also updates the assertion in DoubleToFloatInstr::Canonicalize
which verifies that DoubleToFloat instruction can be used only
in certain cases.

AOT transformations (mixin deduplication and TFA tree shaker) were
using CanonicalName.unbind() in order to make sure that kernel
writer will not be able to write dangling references to the deleted
classes or members (to detect such dangling references earlier).
This conflicts with lazy reading from a kernel file if --from-dill
option is used: lazy reader may read a reference to such class after
unbind() and it creates a new Reference object for such canonical name.
This causes crash later when the fresh Reference is used as it doesn't
have Class node filled in.
The solution is to avoid calling CanonicalName.unbind().
Instead, it is enough to nullify node.reference.canonicalName, which
won't break CanonicalName.reference used by lazy reader.
This crash can be reproduced on tests/language_2/vm/regress_flutter_55345_test.dart
if it is compiled in AOT mode using 2-step kernel generation.
