This is a follow-up to [0]. That CL changed dart2wasm's modular
transformer to issue an error if `dart:ffi` is imported.
Users of packages that have specialized code for the VM (which supports
FFI) use conditional imports based on `dart.library.ffi`. We don't want
the VM-specific code to be used for web in dart2wasm (as dart2wasm
doesn't support the entirety of `dart:ffi`).
As a result we're going to make `dart.library.ffi` be false in
coditional imports (as well as in
`const bool.fromEnvironment('dart.library.ffi')`).

Previously, if a record literal had named fields, type inference of
the literal fields would happen as part of the process of
hoisting. This was a problem because the hoisting process requires
visiting the fields in reverse order, so as a result, the order in
which subexpressions were type inferred was the reverse of the order
in which they would be executed, leading to unsound type promotion
behavior.
Fixes#55914.

No client of the VM uses this flag, only tests, and this flag was always
set to false in AOT mode. Thus, remove uses of this flag and instead
always lazily create dispatchers as needed when resolving method names
in JIT mode.
Remove the implicit value of `allow_add` for some Resolver
static methods. For callers that previously depended on the implicit
`true` value (which includes the AOT precompilier), pass `true` for
uses in the compiler and pass `!FLAG_precompiled_mode` for uses in the
runtime. Assert that `allow_add` is false when these methods are invoked
from the precompiled runtime.
Remove Resolver static methods that are no longer used.

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.

This never worked. It was silently accepted, at least if the future had no listeners, then any later attempt to use the future would cause a stack overflow or other impossible results.
Moves some `_Future._complete` call out of try-catch.
The `_complete` shouldn't throw (but before this fix it could).
Moving them out of the `try`/`catch` makes such errors be reported
as unhandled, instead of catching them and trying to complete the same
future again with an error, when it's possibly in an inconsistent state.

Currently the type of a static field is only based on the dart type, not
inferred types. This can mean that the type of such field is e.g.
`dynamic`.
Though the return type of the initializer function used the unboxing
information.
=> There was an invariant that if we use `null` to signal uninitialized
in the global, then calling the initializer will also result in a
non-nullable reference type.
=> This was invariant was broken by recent changes to dart2wasm that
take advantage of TFA-inferred unboxing information.
=> We fix this inconsistency by ensuring the wasm global's type is the
same as the initializer function's return type.

When analyzing the type test implied by a pattern, flow analysis uses
three variables to control promotion behavior:
- `matchFailsIfWrongType`, which indicates whether flow analysis needs
to account for the possible control flow path resulting from the
type test failing. (This is `false` for cast patterns, because in
the case where a cast pattern fails, an exception is thrown).
- `matchMayFailEvenIfCorrectType`, which indicates whether flow
analysis needs to account for the possible control flow path
resulting from the type test succeeding, but some other check
causing the match to fail. (This is `true` for most list patterns,
because the list pattern will fail to match if the list has the
wrong length).
(Note that `matchMayFailEvenIfCorrectType` doesn't account for the
fact that a pattern match might fail due to failure in a subpattern
match; this is automatically handled by the fact that flow analysis
walks through the complete pattern in the order in which it
executes.)
- `coversMatchedType`, which indicates whether the type test is
guaranteed to succeed due to a subtype relationship between the
matched value type and the type being tested (e.g. a `num x` pattern
is guaranteed to succeed if the matched value type is `int`).
In the case where `matchFailsIfWrongType` is `true`,
`matchMayFailEvenIfCorrectType` is `true`, and `coversMatchedType` is
`false`, flow analysis must account for the fact that there are two
ways that the pattern match might fail: the type test might fail, or
the type test might succeed but then the pattern match might fail for
some other reason.
Before this change, this was done incorrectly, and flow analysis only
accounted for the possibility of the type test failing.
