This transformation replaces the body of _getMainClosure in
dart:_builtin with `return main` for the script's main if there is one
and removes the body if there is no main.
Without this transformation fasta will compile `return null` and dartk
will compile `return throw new NoSuchMethodError...`. Both of these
patterns will be patched in the VM when dart:_builtin is compiled from
Kernel.

Some of the factories methods don't accept yet enough tokens, and fileOffset(s) for them are set externally.
Also PropertyGet, SuperPropertySet, MethodInvocation which are used in accessors, are not converted yet.

- defines a .gn target for patched_dart2js_sdk
- changes patch_sdk.dart to handle a dart2js target
- adds support in fasta to understand the `native` clause still used by dart2js
- add option to fasta to know whether it is generating kernel for the vm or dart2js
I'm not excited about how I added the target distinction in fasta, the reason I
did so is that it affects the behavior in several ways: in how we handle
`native`, in the libraries that are included by default in the platform.dill file,
and in the transformations that need to be done. I'm happy to change the
approach.

This method doesn't really belong in AstFactory, because it's not used
by BodyBuilder; it's used by KernelFieldBuilder, which always builds
kernel objects. We only need to abstract the objects that are created
by BodyBuilder, since only BodyBuilder is going to have to be capable
of building analyzer ASTs.

This is a necessary prerequisite for re-using BodyBuilder to make
analyzer ASTs, since analyzer ASTs use tokens rather than offsets to
keep track of file positions.

from front_end/lib/src/fasta/analyzer/
to analyzer/lib/src/fasta/
analyzer_compile and compile_platform_dartk moved
from front_end/lib/src/fasta/analyzer/
to front_end/tool/_fasta/
front_end/src/fasta/testing/* continues to have some shared testing logic,
- logic to compute the patched sdk is moved up one level
- TestContext, Run, and suite.dart (which depend on analyzer) moved to pkg/front_end/test/fasta/testing/
- only a copy of TestContext is duplicated under pkg/kernel/test/closure/.

1. A --platform flag is added to dart to give a path to a Kernel
binary for the platform libraries (as produced by building the
runtime_kernel target).
2. This binary is used for bootstrapping. Since it contains libraries
other then the VM's bootstrap libraries, they are also loaded.
3. The frontend does not send any library with a dart: import URI
scheme. Note that it does not (yet) prune the canonical name
table, which will contain a lot of unnecessary names used for
internal linkages in the platform libraries.
4. There is a single dependency in the platform libraries on the
script: _getMainClosure in dart:_builtin. This is patched after
the script is loaded.
