Chinmay Garde aa64d1d2e6 Allow building Dart with Fuchsia SDK enabled buildroots.
The Fuchsia SDK can now be consumed by non-Fuchsia buildroots to produce
Fuchsia artifacts.

The Fuchsia SDK comes with a JSON manifest that describes the various SDK
"parts". GN targets are stamped for each of these parts. The location of these
GN targets can be configured. That location is set to |fuchsia_sdk_root| in
each buildroot. This variable is defined in //build/fuchsia/sdk.gni in each
buildroot. For buildroots that don't care or know about the Fuchsia SDK, that
file may not exist. This is why, the import of that file is guarded behind
the is_fuchsia flag. When the Fuchsia SDK is enabled, that file will define
values for two required variable |using_fuchsia_sdk| and |fuchsia_sdk_root|.

The first flag defines if the SDK is being used. If unset (but defined), the
builds are in-tree. Eventually we want only SDK builds. |fuchsia_sdk_root|
is set to the spot in the buildroot where the GN targets for the SDK parts
are stamped.

Aart Bik ec15148db2 [dart/fuzzer] no target on unsupported build targets
Rationale:
This if "hides" the dart_libfuzzer target for
build targets that do not support the fuzzer tool
(e.g. no asan, ia32, etc.). This makes "build all"
possible again, and yields "unknown target 'dart_libfuzzer'"
for unsupported case. Also updates README accordingly
and fixes some formatting.

Clement Skau 907c514c89 [SDK] Adds build targets, wrappers and SDK builds for Dart AOT.
Adds:
- dart2aot, a script similar to dart2js which compiles my.dart to my.dart.aot.
- dartaotruntime, a minimal Dart runtime that only runs AOT blobs.
- some extra tooling like gen_kernel and gen_snapshot used by the above.
- build rules for all of the above, including adding it to the full SDK builds.

Martin Kustermann f5d1229081 Reland "[VM] Inline ClassID.getID() eagerly, extend pattern matching logic to recognize it, use it to special case ascii decoding"
This change extends/fixes the exiting "pattern recognition" which tries
to recognize the pattern

  v2 <- LoadClassIdInstr(v1)
  BranchIf v2 == IntegerConstant(cid)

Furthermore we start inlining the recognized `ClassID.getID` method very
early in the pipeline.  This allows the VM to recognize the above
pattern and insert redefinitions before the actual inlining pass.

Furthermore we special-case two very hot methods in utf8 decoding by
manually having two loops, one of which is guarded by a class-id check
against the _Uint8ArrayView class, which is most common.  (In the future
we would like to unify the typed data layouts so we no longer need to
use `ClassId.getID`, thereby also allowing non core library code to use
this).

This improves dart-aot by
  * 31%+ for a protobuf decoding benchmark we care about

Martin Kustermann d7cf6959bb [VM] Inline ClassID.getID() eagerly, extend pattern matching logic to recognize it, use it to special case ascii decoding
This change extends/fixes the exiting "pattern recognition" which tries
to recognize the pattern

  v2 <- LoadClassIdInstr(v1)
  BranchIf v2 == IntegerConstant(cid)

Furthermore we start inlining the recognized `ClassID.getID` method very
early in the pipeline.  This allows the VM to recognize the above
pattern and insert redefinitions before the actual inlining pass.

Furthermore we special-case two very hot methods in utf8 decoding by
manually having two loops, one of which is guarded by a class-id check
against the _Uint8ArrayView class, which is most common.  (In the future
we would like to unify the typed data layouts so we no longer need to
use `ClassId.getID`, thereby also allowing non core library code to use
this).

This improves dart-aot by
  * 31%+ for a protobuf decoding benchmark we care about

Vyacheslav Egorov 2c83eb550e [vm] Integrate dart binary with Crashpad on Windows.
dart binary would instantiate CrashpadClient if DART_CRASHPAD_HANDLER
and DART_CRASHPAD_CRASHES_DIR environment variables are set.

- DART_CRASHPAD_HANDLER should contain the path to the crashpad_handler
binary that would handle the crash and write minidump;
- DART_CRASHPAD_CRASHES_DIR should contain the path to the crashpad database
which would be used to store minidumps.

Rewrite --copy-crash-dumps support on windows to use Crashpad integration
instead of editing Windows registry.

Embedding crashpad required to roll a new zlib version because Crashpad
depends on the zlib. This version of zlib is buildable with its own
BUILD.gn so our custom BUILD.gn is removed.

Martin Kustermann 5c9a8d8cb5 [VM] Add $target_gen_dir/gen_kernel_bytecode.dill.d to outputs of GN action, to ensure directory is created before action is run
This fixes flaky build failures on our bots.

To reproduce the original issue:
  % rm -rf out/DebugX64
  % tools/build.py -mdebug -ax64 gen_kernel_bytecode_dill
  output: Error: Unable to open snapshot depfile: .../out/DebugX64/gen/runtime/bin/gen_kernel_bytecode.dill.d

This change seems to force GN to create the parent directory of outputs before
running the action.
