Move optimized handling of Double.truncateToDouble, floorToDouble,
ceilToDouble, floor and ceil from flow graph construction to
the canonicalization pass.
This is needed in order to maintain stable flow graphs between
app-jit snapshot training (which is performed with --target_unknown_cpu)
and running from app-jit snapshot without --target_unknown_cpu.

Before this CL, becase of optimizations, coverage of some of these goes
away, making coverage unreliable.
I believe this fixes the issues for "regular" runs (at least it seems to
be stable on the CFE coverage tests).
If setting `--optimization-counter-threshold=-1` there'll still be
trouble though and we would have to also insert these calls in the start
of FunctionBody and the start of FieldInitializer for it to produce the
same results.

This CL moves native assets resolution to the embedder.
The Dart VM looks up the asset path (for example
`['relative', 'foo.so']`) with the asset id. The embedder defines
callbacks for asset loading, and returns a handle to the dylib.
Then the VM calls the embedder again with `dlsym` to lookup the symbol.
The Dart VM & kernel compiler are responsible for the asset id to
asset path mapping. The kernel compiler compiles it into the snapshot
and the VM looks it up in the snapshot.
Relative paths are resolved relative to the isolate script uri (kernel
snapshot, jit snapshot, aot snapshot, or `dart compile exe` result).
The embedder is responsible for remembering the script uri it set when
spawning the isolate group.
This CL does not add `dlclose` or `dladdr` embedder callbacks yet.

This adds support for printing the DTD connection information to stdout
when --print-dtd-uri is passed.
This change also fixes an issue where DDS would fail to spawn an isolate
with the DTD snapshot when DDS was running in AOT mode. This means the
SDK must be shipped with both AppJIT and AOT DTD snapshots, at least
until dartdev is moved to run from AOT.

The DART_VM_OPTIONS environment variable allows for users to specify a
set of VM options to be processed by the Dart runtime in a
self-contained executable created by `dart compile exe`.
DART_VM_OPTIONS should be a comma separated list of options and flags
with no whitespace. Options that accept multiple values as a list of
comma separated values are not supported and will result in argument
parsing failing.

We were exporting all symbols to the dynamic table so that they could be looked up using `dladdr` for the profiler and backtracer. The symbols include our statically-linked libcxx, which can create trouble when another DSO has a different version of libcxx. Now we export only the VM embedding API functions (`Dart_*`) and use a specially produced table to do the symbolization.

Creation of AppJit snapshot will not include the source of [Script]
objects (see `UntaggedScript::snapshot_to`). As a result there's no
point in letting the CFE embed the sources into the kernel if we
only use it to create an AppJit snapshot.
This is also in line with build rules for our dart-sdk, where we do the
kernel compilation separately, see utils/application_snapshot.gni:
```
template("application_snapshot") {
...
# Build the kernel file using the prebuilt VM to speed up the
# debug and simulator builds.
prebuilt_dart_action(target_name + "_dill") {
...
args = [
...
"--no-embed-sources",

[[[

The bulid rules generate an appjit snapshot or a kernel file under
dartdev.dart.snapshot depending on whether the target_cpu is the same as
the host_cpu.
Generation of the additional dartdev.dill file is not needed because of
this, the logic to start the dartdev isolate tries to load
dartdev.dart.snapshot as an appjit snapshot first and if that fails it
tries it as a kernel file.
