This CL implements a slightly altered compilation process for `dart
compile` on MacOS. Instead of the traditional approach of
concatenating a dart snapshot with the dart runtime, this new
implementation uses a new MachO segment to store the snapshot. Doing
so ensure users can properly sign the resulting binaries.
The dart runtime has also been updated to look for the snapshots in
this new segment.
There are new unit tests ensuring the dart runtime can correctly
identify MachO-formatted executables and an end-to-end test ensuring
`dart compile` produces code that has the new segment and produces
code that can be signed.

Handles cases where the SDK is installed on a path which includes
percent encoded characters. The OS doesn't decode these characters, so
decoding them before trying to load a snapshot with said characters in
their path will result in files not being found.

Original change is in Patchset 1. I erroneously assumed DART_PRECOMPILER
was only used AOT compilation (it is also used for JIT snapshots).

The Dart runtime will be able to load snapshot blobs appended at the end of
itself.
This is a step on the way to a self-contained native executable.
Tested:
$ dart2aot hello_world.dart hello_world.aot
$ <Some steps to hand-craft appended binary ..>
$ dartaotruntime_plus_hello_world.bin
Hello, world!

In addition, this removes support for seeding the VM isolate snapshot with Instructions and referencing those Instructions in the isolate snapshot. This was leftover from an earlier experiment to share Instructions between a Core-JIT snapshot and App-JIT snapshots. Removing this reclaims the sign bit on Instruction offsets.
Add missing cases to TypeTestingStubFinder::StubNameFromAddresss.
