Rationale:
This fixes the following three issues to get byte-exact
snapshot size difference reporting, which makes optimizing
for code size a lot easier.
Issues:
(1) reports the slightly more accurate raw size
(2) accumulates dups in the json
(before we only did bookkeeping for one)
(3) avoid non-deterministic parts in names
(this resulted in reporting baffling method size
differences against the same layout, even though
the aggregate difference added up to 0).

* Type arguments are moved to global object table (and de-duplicated).
* Finalize non-recursive generic types at bytecode generation time.
* Constants are moved to global object table (and de-duplicated).
* ICData creation is avoided for direct calls.
* Interface calls reference target member instead of selector name.
Size of a dilp files: 17868K => 15896K (-11%).

When creating a closure, receiver is loaded in order to obtain
instantiator type arguments. That access was not capturing
receiver, if a closure was created inside another closure.

This achieves consistency with similar getters in the API.
This is technically a breaking change, since it changes a published
part of the Kernel API. Since the constants API is relatively new and
so far only used internally in the AOT compiler, the change is
expected to be unproblematic.

An invalid constant is (currently) represented by an unevaluated
invalid expression. Using this instead of null fixes 63 out of 125
CFE constant-evaluation crashes with constant-update-2018 and
correctly signals 26 more previously-missed compile-time errors.

In package-split mode, bytecode generation is performed separately for
each package. Previously, dropping AST was done right after generating
bytecode. However, dropping AST for a package makes it impossible to do
constant evaluation in other packages which import the package with dropped
AST. This breaks bytecode generation for subsequent packages.
To work around this problem, in package-split mode AST is removed
temporary until dillp file is written. After that, removed AST is restored
back.

Fasta allows some non-const static field access in constant contexts
which leads to the constant evaluator trying to evaluate them. Signal
an error instead of crashing. This will double-report errors for the
cases that Fasta already catches, and we should fix that
double-reporting.
Fix unbounded recursion in printing unevaluated constants (writeNode
called visitUnevaluatedConstant which called defaultConstant which
called writeNode...).
Fix a spurious trailing comma in printing of instance constants.

Make the constant evaluator take an explicit error reporter so we have
to opt in to using the "simple" one that reports errors in an ad hoc
way. This is the start of a change to use Fasta-controlled error
messages throughout and eventually get rid of the simple error
handler, and to continue constant evaluation after the first constant
error.

Validating the class hierarchy requires subtype tests. Previously,
Fasta has worked around this by computing the hierarchy twice, as
well as visiting the hierarchy several times. In order to improve
performance of modular compilation, we're working on changing this.
To enable creating a TypeEnvironment without a hierarchy, we're
removing the field from the API.

MethodInvocation nodes which have field or getter as interface target
actually correspond to 2 calls: 1) getter; 2) implicit call() on the result
of the getter.
While this was correctly modeled in summaries in TFA, it is not correct
to attribute such MethodInvocation nodes with results of the inference,
as results correspond to an each distinct call. To fix this, Call
statements in summaries are created without attaching them to a
corresponding kernel AST node.

This flag was always true so we can remove it and specialize the
remaining code that used it. The only code that used it was in the
Dart VM's async transformation.
Specializing that code led to some unused fields in the async helper
class which were removed. This triggered me to look at core types
which seems to have a lot of unused stuff.

Original PR was reverted because it broke hot-reload bots. This CL adds steps to initialize kernel_service compiler for child isolate. Compiler is needed to support hot-reload request. Child isolate's compiler is created from full kernel file produced by main isolate's compiler. Changes since original PR are pkg/vm/bin/kernel_service.dart in pkg/vm/lib/incremental_compiler.dart.
Further this CL changes kernel fingerprint calculation for interface types so it calculates the hash of the canonical names themselves, rather than indices(that might change from one compilation to another).
This reverts commit 63fd8f63e6.

expectation is that many of the places that now pass false explicitly
really just want the default, but that will be verified separately and
