Build another varient of dart_bootstrap targeting the host architecture to ensure reasonable Observatory build times.
Remove assert assuming a root script, which does not exist when gen_snapshot builds core snapshots.

These tools are used to support applying source maps to stack traces
and running the Dart dev compiler in the browser as part of an extension.
This CL adds the following files

Allow kernel service request to provide source files(filename, content), which will be used to build up MemoryFileSystem instance. MemoryFileSystem instance will be used instead of PhysicalFileSystem instance.
Immediate need for this is to support VM unit testing, where small Dart scripts that have to be parsed are hardcoded in the unit tests.

Remove hack in bin/snapshot_utils.cc that avoided building a true app-jit snapshot for ARM, ARM64 and MIPS because of the multiple invocations above.
Add GN flags to choose to build script snapshots instead of app-jit snapshots, avoiding a slow training run inside a simulator.
Fixes#29580.

- 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 speeds up dartdevc on hello world from about 600ms to about 150ms.
OTOH, it also increases the snapshot size from ~4.6M to ~31M (the
latter is just under the size of the dart2js snapshot).
I tried this before. This may break again on windows - if so, i'll revert.

Without this, we risk creating two different libraries at runtime. One
named file:///something/ and one named package:front_end/something.
These libraries are different and if enums from one gets mixed with
the other, you get very confusing errors (to apparently identical enums
aren't equal).

This adds a class CanonicalName that can represent a library, class,
or member. All references now go through a Reference object, which is
linked to both the AST node and its CanonicalName, so either can be
created first.
dartk now accepts multiple input files:
- If multiple dart files are given, they are all compiled.
- If multiple binaries are given, they are linked together.
Mixed dart and binary input is not supported by dartk.
dartk now has a flag --include-sdk which includes the entire SDK in
the output. This is so the SDK can be compiled alone and then linked.
Example of compiling separately and then linking:
dartk foo.dart -o foo.dill
dartk main.dart -o main.dill
dartk --include-sdk -o sdk.dill
dartk main.dill foo.dill sdk.dill --target=vm --link -o program.dill
dartk still has incredibly slow cold start due to the analyzer loading
the dart sdk, so this does not actually speed things up at the moment.

We are not switching yet, but now everybody can try fasta by doing:
$ dart -DDFE_USE_FASTA=true --dfe=utils/kernel-service.dart hello.dart
Note that when using fasta we expect that patched_sdk contains platform.dill
Kernel binary containing compiled patched sdk. This file can be obtained by
doing:
$ export DART_AOT_SDK=<path-to-patched_sdk>
$ dart pkg/front_end/lib/src/fasta/bin/compile_platform.dart \
${DART_AOT_SDK}/platform.dill
We are also adding --use-fasta to testing script to allow end-to-end testing
of fasta (though platform.dill file needs to be generated manually prior to
running tests):
$ tools/test.py -c dartk -m release -a x64 --nobatch --use-fasta
Current test status:
$ tools/test.py -c dartk -m release -a x64 --nobatch --use-fasta

Target-specific modular transformations have to be able to cope with
external libraries. Target-specific global transformations should be
optimizations, and not required for correctness, since a simple linker
may choose not to perform them.
Make mixin resolution modular by making it fail when a mixed-in class
comes from an external library. (We cannot mix in such a class because
we do not necessarily have all class members.)

- Update app snapshots without code to not rewrite the VM isolate snapshot, as already done by app snapshots with code.

This makes doing an SDK build in the Fuchsia tree easier.
The previous attempt at this change failed in gyp builds targeting xcode.
They failed because input lists for actions of the same target (e.g. the
actions for dartanalyzer) are merged and de-duped when the lists contain
relative paths, but merged and *not* de-duped when the lists contain
absolute paths. gyp rejects xcode files that it generated itself
when they contain duplicate entries.
This CL works around that bug, by using absolute paths in the GN build
and keeping relative paths in the gyp build.
