Changes in this CL:
- Updated CompilerContext:
- it now contains a ProcessedOptions object
- it no longer depends on CompilerCommandLine/CommandLine
- it delegates to ProcessedOptions.report so all error reporting
goes to one single place.
- use "withContext" term instead of "withGlobalOptions" to be
more clear about the intent
- Changes in public API
- added more options that correspond to flags in command-line
fasta tools
- default onError is different: we now use the
command_line_reporting report, which prints and throws
on fatal messages, but doesn't throw eagerly on all messages
as before.
- introduced "printMessages" option: make it easy to have
both onError + command_line_reporting (kernel-service.dart
is the main use case at this time, other ideas welcome!)
- renamed CompilationError to CompilationMessage
- Other changes
- set exit code is done on report, not on format
- fixed corner cases not covered in previous CL
- error reporting with missing-main needs to happen with
a context
- missing error cases when inferring .packages and input
URIs are not file:* URIs
Ideas for follow up after this CL:
- combine ProcessedOptions and CompilerContext into a single class
(or extend one from the other)
- switch onError to a stream

Original CL had a bug that wasn't visible unless you delete your
out/ReleaseX64/patched_sdk folder.
Patchset #1 is the original CL, patchset #2 shows the fix.
This reverts commit 4aadfe09df.

This CL tweaks the public APIs in package:front_end, and
starts using those APIs outside the package. For example, this
removes 9 uses of DillTarget, so it is not longer mentioned
outside pkg/front_end and the analyzer_target.
Actual changes:
- in package:front_end
* added kernel_generator_impl: new file contains code that
used to be in kernel_generator. Code has some modifications:
it uses a single canonical-root when loading summaries, and
it supports generating both outlines and kernel in one go.
* removed code that didn't belong here:
a. most of calculating deps for .GN moved to patch_sdk
b. vm-specific outcomes moved to kernel-service
* updated how `native` is implemented, so we can more easily
support dart2js and ddc
* updated how we check where `int`, `bool`, etc can be implemented.
* added support "hermetic mode" in modular builds
('chaseDependencies = false' option)
* moved `trim` step out of fasta, and for now call it only within
the public API. This is not yet exposed, and I stopped covering it in
most tests (now only covered in shaker tests). The plan is to add
tests for the public API covering this in the future.
* removed `uriToSource` when serializing outlines
* added unit tests for public APIs
- patch_sdk
* use the public API to craete platform.dill, outline.dill (now
500K insted of 3Mb because it excludes sources), and vmservice_io.dill
* moved here logic internal to .GN
- kernel service
* use the public API
* moved here logic that depends on VM internals (e.g. status enum,
compilation results)
- package:compiler
* use the public API in tools and unit tests
* simplified patched-sdk generation: no more extending fasta's internals
- package:kernel
* fix bug in deserialization: initializers and other lists were
overwritten accidentally with external definitions.
* updated unit tests, moved shared logic to frontend/src/fasta/testing

This also makes perf_test.dart do something useful. It now executes perf.dart on
a small file from pkg/front_end. This may help to detect early when the
peformance bots will see a failure. I've only tested this in linux, but given
that's the OS of the perf bots, I'm ok skipping this in other OSs.

This carries a number of benefits:
- It allows the front end to trivially support schemes other than
"file:" (e.g. "http:") by allowing the client to supply a FileSystem
implementation that handles them.
- It is more consistent with the functionality of the ".packages" file
(which allows packages to map to any kind of URI).
- It allows the "bazel root" feature to be rewritten to use a magic
scheme rather than a magic path. (This eliminates concerns about
the magic path overlapping with a user's use case). Note that this
feature has been renamed to "multi root" since it is sufficiently
generic to be applicable to build systems other than Bazel.
- It reduces the risk of forgetting to use the front end's FileSystem
abstraction to access the file system, since the native file system
interfaces do not accept URIs.

I'm happy to split the style/refactorings as separate CLs if you prefer. Here is a summary of the changes:
- update the reported strings to match the names expected by our benchmark runners ("unlinked summaize + parse" => "unlinked_summarize")
- invert the benchmark results (like Paul did in 2551533003)
- stop counting input-size while scanning, count that separately once
- combine the multiple summarization steps into a single function
- clean up the logic that dispatches into each benchmark

This CL adds support for using sdk summaries when building kernel using the
front_end entrypoint. I didn't expose this functionality in the dartk binary,
I'm hoping we can delay doing so until we integrate dartk and front_end.
I also switched front_end/tool/perf.dart to use kernel_generator directly.
This makes some observable difference for small scripts, but not so much with large apps like dart2js. Makes sense considering that the sdk is about 2Mb, and dart2js is 6Mb of sources.
The most interesting number I got is building the a library kernel file (not the whole program) for a small hello-world script on a warmed up vm:
no summaries: 500ms
with summaries: 30ms

In kernel, library import URIs now support an "app" scheme as an
alternative to the "file" scheme, representing a path relative to
the application root.
dartk takes an --app-root flag giving the application root. If none
is given, file URIs are used instead.
The intention is that kernel binaries should not carry irrelevant
path information, such as the path to the home directory of the
user who compiled a given file.
It is not the intention that end-users should see an app URI.
Import paths are currently not shown to users at all, and if we need
to do this, they should be translated to file paths first.
In theory we could stick to file URIs with relative paths, but the Uri
class from dart:core makes this difficult, as certain operations on it
assume that file paths should be absolute.
Source mapping URIs are not yet affected by this change.
