Today, support for expression evaluation in DDC uses a lot of
information. To properly support compiling expressions in arbitrary
frames, we consume source-maps, module metadata, and full kernel
components at various stages of the process. This data is already
plumbed and available for non-sdk modules in our debugging systems
(frontend-server, webdev, g3), however it is not available the Dart
SDK module itself. Because of that, the expression compiler today
rejects all expression evaluation requests when the target is a Dart
SDK library.
Until the fix the availability of this data everywhere, we believe
we can support a limited form of expression evaluation: only
evaluation of libary level expressions. Basically, expressions
where scope data is not necessary and kernel outlines are sufficient to
compile the expression.
Here we introduce logic to recognize the first offset location of a
library, which is a clear indicator that no scope data is needed and
a library level expression evaluation is being requested.
This change is an attempt to help resolve
https://github.com/flutter/devtools/issues/7766. Note: just like
changes were needed here in the worker and test-compiler files, it
is possible that some change may be necessary in dwds and other
parts of the pipeline. Additional validation will be needed after
this lands.

When iterating on core library changes or changes in the AOT compiler
many seconds are wasted waiting on gen_kernel/compile_platform to
parse Dart code. This happens because we are running these tools
from sources on prebuilt Dart SDK.
This CL allows SDK developer to opt-in into AOT compiling these
tools by adding `precompile_tools=true` to their DART_GN_ARGS.
AOT compilation is performed using prebuilt SDK - so these
executables do not need to be recompiled if core libraries or
VM changes reducing iteration cycles.
pkg/vm/tool/precompiler2 is tweaked to detect when DART_GN_ARGS
contains `precompile_tools=true` and use precompiled
gen_kernel.exe instead of running it from source.
Using precompiled compile_platform takes vm_platform_strong.dill
build from 20 seconds to 3 seconds.
Using precompiled gen_kernel takes small benchmark build from
~10 seconds to 2 seconds.
This relands 5cda2a871c with fixes
for Flutter build.

The change adds a new reduction that recognizes the construction of a type environment from components
HTypeBind(HTypeEval(env, e1), HTypeEval(env, e2))
and replace with an equivalent expression that constructs the same derived type environment directly
HTypeEval(env, ...e1...e2...)
This change speeds up the benchmarks that iterate `Map.entries` by roughly 10-25%.
---
Type arguments are passed as separate values [1]. This means that the generative constructor factory `MapEntry<K,V>(this.key, this.value)` has four parameters - `MapEntry$(key, value, $K, $V)`. The passed arguments usually come from the same place, perhaps extracted from the type of the current object, `this.$ti._eval("1")` and `this.$ti._eval("2")`.
Inside `MapEntry$`, the type parameters are re-assembled into a type environment:
$K._eval("@<0>")._bind($V)
which is used to construct the object type
$K._eval("@<0>")._bind($V)._eval("MapEntry<1,2>")
After inlining:
$K = this.$ti._eval("1");
$V = this.$ti._eval("2");
$K._eval("@<0>")._bind($V)._eval("MapEntry<1,2>")
After GVN, and reducing the adjacent `._eval("1")._eval("@<0>")` to `._eval("@<1>")`:
t1 = this.$ti
t1._eval("@<1>")._bind(t1._eval("2"))._eval("MapEntry<1,2>")
The new reduction gives us:
this.$ti._eval("@<1,2>")._eval("MapEntry<1,2>")
which can be reduced further by combining adjacent HTypeEvals:
this.$ti._eval("MapEntry<1,2>")
[1]: It would be better to pass the type arguments as a single Rti object to avoid the extract-recombine pattern, but changing the calling convention is a more extensive change. In the meantime, this reduction cleans up the extract-recombine pattern when inlining brings the parts together.

Knowing whether Dart code is running in a WebAssembly context is useful
to potentially select different code paths exploiting differences in
JavaScript and WASM behavior or simply to report the information to
users (e.g. for crash reports).
Without such a constant, one has to rely on implementation differences
such as `identical(0, 0.0)` or check the available `dart:` libraries.
Both are error-prone, so having a reliable constant as an alternative
makes this easier.

I convert the `noSuchMethod` tests to (imho) simpler tests of what
property access of `e` or `d` or `D` would look like on an int, via
extension getters.
The noSuchMethod test as it was written cannot be executed at runtime,
because (as of Dart 2, I think, maybe earlier), property access on
expressions is a compile-time consideration. And I think as a compile-
time error test, it's hard to see what it's testing.
