Jens Johansen 80860e7fb7 [kernel] Stream kernel_reader 
Mostly stream kernel_reader, i.e. the code that sets up the libraries,
classes, methods etc.

Mostly because it still takes a "Program" ast node, and looks at the
"Library" ast nodes to get their kernel offset in the binary.
Currently the scripts (containing breakable points etc) are also created
from the ast nodes.

The rest is now streamed.
This also means that more ast visitors could be deleted.

Jens Johansen be9a3043aa [kernel] Make fasta call a new constructor on FallThroughError 
On a switch fall through error, Fasta currently generates
```
throw new core::FallThroughError::•();
```

which generates the error-message via the VM:
```
'null': Switch case fall-through at line null.
```

This introduces a new constructor taking a url and a linenumber,
which then can give a better error message.

Paul Berry 1594006758 Print static types of conditional expressions. 
I want to start testing that Fasta sets the static types of
conditional expressions correctly, so I need Fasta's expectations
files to include them.

This CL just adds the static types to the printing logic in
ast_to_text.dart and updates expectations so that the tests continue
to pass.  I will make behavioral changes to Fasta in future CLs.

Paul Berry be01632bc0 Fix type inference of getters that "override" setters and vice versa. 
Normally getters and setters are considered distinct and unrelated by
the type inference algorithm.  However, if a getter has no declared
type and doesn't override anything, then we fall back on inferring its
type from an inherited setter, and vice versa.

Kevin Millikin 0489249d29 Proper sequencing of _asyncStackTraceHelper in Kernel 
This helper function was being called before its argument was
initialized so it was passing null.  Instead, it should be called
after its argument is initialized.

Because the initialization happens in Kernel code, it is simplest to
insert the call explicitly in Kernel code as well as part of the async
transformation.  This has the consequence that we now call the helper
function even when the flag causal_async_stacks is false.

Fixes #29771.

Jens Johansen 0a1583aa04 [kernel] Fix assert message. 
This mimics the behaviour of the source-based pipeline,
i.e. instead of "manually" calling _AssertionError._create and giving
the correct parameters (wrong parameters, actually), use the helper
method _AssertionError.ThrowNew.

Closure conversion can now be run on a part of a program.  It allows
using closure conversion in kernel-isolate.  It comes at a cost of
temporarily sacrificing implementation of tear-offs via closures; VM
mechanism for tear-offs is used for now.

Paul Berry 5c3dd4b11b Change MethodInvocation.interfaceTarget from a Procedure to a Member. 
It's possible for the interface target to be a field, e.g.:

    typedef void F();
    class C {
      F f;
    }
    void g(C c) {
      c.f(); // Interface target is C::f
    }

Also, this CL fixes MethodInvocation.getStaticType() in the case where
the interface target is a getter.

that this is initial compilation, i.e. nothing read from the cache yet.
