The Dart2JS team has agreed that this mode of compilation is no longer worth investing in at this time and its existence adds some overhead to other feature work so it is worth fully removing. In the future we may revisit this mode of compilation. Below is some more context for any future exploration in this space.
What didn't work with modular analysis:
- current modular analysis was computing impacts, which were dense (50% of the size of kernel)
- using it moved work to a modular phase, and cut Phase1 in half however end-to-end time was not better
- data overhead was very high
- it made it much harder to maintain invariants throughout the pipeline: the data is tightly coupled with the kernel AST, making it hard to make late modifications to the AST.
How to potentially make it better:
- make the data much more sparse
- make the data more independent from the kernel AST so that transformations are not breaking
- reduce the critical path in a more substantial way.
Note: We retain and ignore the commandline flags used for modular analysis in order to avoid breaking build pipelines that were passing them. We may remove these at a later date.

This CL removes static fields for storing the `@Native`'s function
addresses. Instead, the function addresses are stored in the object
pool for all archs except for ia32. ia32 has no AOT and no AppJit
snapshots, so the addresses are directly embedded in the code.
This CL removes the closure wrapping for `@Native`s. Instead of
`pointer.asFunctionInternal()()` where `asFunction` returns a closure
which contains the trampoline, the function is compiled to a body
which contains the trampoline `Native()`. This is possible for
`@Native`s because the dylib and symbol names are known statically.
Doing the compilation in kernel_to_il instead of a CFE transform
enables supporting static linking later. (The alternative would have
been to transform in the cfe to a `@pragma('vm:cachable-idempotent')`
instead of constructing the IL in kernel_to_il.
To enable running resolution in ia32 in kernel_to_il.cc, the
resolution function has been made available via
`runtime/lib/ffi_dynamic_library.h`.
Because the new calls are simply static calls, the TFA can figure
out const arguments flowing to these calls. This leads to constant
locations in the parameters to FfiCalls. So, this CL also introduces
logic to move constants into `NativeLocation`s.

This extracts the code that finds "examples/api" paths in code from the navigation code so that it can be re-used by LSP's DocumentLink request.
This allows the links to be more visible in the editor (they are underlined and clearly clickable like hyperlinks, whereas definition required you to hover and hold Ctrl before you'd seen an underline in VS Code).
Example: https://github.com/Dart-Code/Dart-Code/assets/1078012/be9db467-dbc9-4206-9dd5-f8ca72d95596
There may be an argument for making this more general (so that links other than example/api could be detected) but for now the goal was to make these existing links more obvious.

The implementation of `~/` is a bit more complicated than other
operators as it needs to handle some special cases, so we currently
don't generate inline code for it.
This causes generating indirect calls to `~/` in some cases even when
the static Dart type of the arguments are `int`s, see [1] for details.
Update the intrinsic matcher to specially handle this operator by
calling `_BoxedInt._truncDiv`, which is then inlined.
This leads to huge performance wins in [2] as typed data `length`
getters currently compiled to indirect calls to `~/`.

Refactor libraries so that JSCM will only use `JSStringImpl` class for
strings.
The goal is to disentangle the native string classes and `JSStringImpl`
and start testing `JSStringImpl` in isolation.
Changes:
- `dart:_string` is no longer available in JSCM.
- Make `int.toString` external to allow patching it differently in JSCM
and normal modes.
`toString` implementations are in `boxed_int_to_string.dart` patch
files.
- `int.parse` now uses JS `parseInt`. However `parseInt` is not
compatible with Dart's `int.parse` so this will cause some more test
failures in JSCM for now.
- Any dependencies to `dart:_string` from JSCM `dart:convert` are
removed. The library implementation now uses JS `TextDecoder` for
UTF-8 decoding.
Note: `TextDecoder` is not available on d8, so text decoding tests
will fail on d8.
JSON encoding and decoding in `dart:convert` will be updated in a
follow-up CL.
- Compiler (translator, constant generator, code generator etc.) is
updated to allocate the `JSStringImpl`s in JSCM.
Initially this will make some JSCM test fail as `int` parsing is not
quite right, those will be fixed in follow-up CLs.

Previously, if field promotion failed both because the language
version was less than 3.2, *and* for some other reason(s), the
analyzer and CFE only reported the other reason(s). The rationale was
that this was better than reporting just that the language version was
less than 3.2, because if a user upgraded their language version to
3.2 in an attempt to get field promotion to work, and *then* found out
that the property in question was unpromotable for some other reason,
that could be quite frustrating.
With this change, if field promotion fails both because the language
version is less than 3.2 and for some other reason, the analyzer and
CFE report *all* the reasons.
