Currently on sim* architectures we use a script snapshot (and not an app
jit snapshot, as we normally do) for the kernel isolate.
-> See utils/application_snapshot.gni:declare_args()
The change in [0] causes a deadlock where we try to compile the kernel
isolate (or rather a script snapshot of it) via the kernel isolate.
This CL fixes all the dartk-sim* builders by allowing us to run the
kernel snapshot from a script snapshot.

Previously doubles was saved as strings in the string table,
with a DoubleLiteral holding a StringReference.
This can cause overhead in both computation time
(converting the double to and from string) as well as size
(e.g. a single usage of the previously unused double 1000000.42
would use (at least)
* 10 bytes for the characters
* 1 byte for the size
* 1 byte for the reference to the string
whereas saving it as a double would simply save the 8 bytes.
On the other hand the string table doesn't contain duplicates so
many usages of the same double will use more space.
The SDK dill file size decreases slightly (< 1 KB).
On a Dart file with 1M different doubles (0.42, 1.42, ..., 999999.42)
added to a list:
Before:
compile and write via fasta (non-strong-mode): 0:12.18
Reading (via dart, eager): 2500-2600 ms
Writing (to null sink) (after reading): 1600-1800 ms
Output dill file (via fasta compile): ~62 MB
After:
compile and write via fasta (non-strong-mode): 0:11.76
Reading (via dart, eager): 2050-2350 ms
Writing (to null sink) (after reading): 400-550 ms
Output dill file (via fasta compile): ~54 MB
Running the dill file is ~the same time, but "Maximum resident set size
(kbytes)" (from /usr/bin/time -v) decreases with ~4%.
On the other side, if it's 1M of the same doubles (0.42), while
compiling is ~the same speed, the output dill goes from 43MB to 50MB.
Surprisingly the "Maximum resident set size (kbytes)" still decreases
though (~3%).
Running flutter test in flutter/packages/flutter:
Before:
```
02:33 +2425 ~18: All tests passed!
02:28 +2425 ~18: All tests passed!
02:28 +2425 ~18: All tests passed!
```
After:
```
02:12 +2425 ~18: All tests passed!
02:11 +2425 ~18: All tests passed!
02:12 +2425 ~18: All tests passed!
```
So that's -12.0267% +/- 3.15253%
File size of a dill file of an arbitrary test using flutter is reduced by ~44 KB (~0.3%).

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.

This reduces small tagged integers on 64 bit platforms from 63 bits to
31 bits plus one tag bit.
This is a step on the way to compile-time-optional compressed pointers
on 64 bit platforms. See more about this at go/dartvmlearnings
This causes a slowdown for some uses of integers that don't fit in 31
signed bits, but because both x64 and ARM64 have unboxed 64 bit
integers now the performance hit should not be too bad.
This is a reapplication of

- Invoke dart2js directly for the build command.
- Use the dart2js executable checked in to the SDK when it is available,
otherwise fall back on the dart VM and dart2js source.
- Manually synthesize a filered `packages` directory out of the source

To enable bytecode generation, toggle kEnableKernelBytecode flag at
the beginning of pkg/vm/lib/bytecode/gen_bytecode.dart.
This will also enable generation of bytecode in platform dill files.
Also, bytecode generation can be enabled using --gen-bytecode option of
pkg/vm/tool/gen_kernel.
In kernel binaries, the generated bytecode and constant pool are
placed into 'vm.bytecode' metadata attached to members.
pkg/vm/tool/dump_kernel tool can be used to disassemble
bytecode and print constant pool.
Differences between generated bytecode and original DBC are
described in pkg/vm/lib/bytecode/dbc.dart.
Format of constant pool is described in
pkg/vm/lib/bytecode/constant_pool.dart.
Currently, only a small subset of Dart language is supported.
Bytecode generator will not emit vm.bytecode metadata for a
member if its body has an unsupported operation.
