Suppose we have code like
if (isDevMode) {
// do foo
} else {
// do bar
}
where isDevMode is const (or can be evaluated as const). In particular,
isDevMode can be controlled by compile-time options, like
bool.fromEnvironment.
We currently eliminate the dead branch during SSA, but that means we do
the work of compiling dead code in the previous phases. Instead, we can
recognize that the condition is const (or effectively const) and
eliminate the dead AST subtree directly.

This test is to ensure that when the language version doesn't include

Since Dart `void` can actually carry values, functions with `void`
return type are translated into Wasm functions returning the Dart
object top type instead of an empty output type list.
Only constructors, setters and imports/exports with void return type
are now given empty output type lists in their Wasm signatures. A new
low-level `WasmVoid` type is added to the internal Wasm types for
specifying explicitly that a Wasm function should have an empty list
of outputs.

Moves JSObject to dart:_js_helper, so that JavaScript objects
can be used with that type in the JS backends. The type then
gets reexported in dart:_js_interop with a typedef.
This is purely for experimentation. This class needs to be sealed
before we can publish this library.

This CL also adds changes how static interop objects are interpreted at the interop boundary. Previously, static interop objects were dartified / jsified like everything else. Now, they are simply boxed.
With this approach, users can now use `Object` when they want conversions and static interop objects when they don't(assuming these objects originate in JS, Dart objects are always fully converted).

On windows we do have a crashpad handler we use to capture coredumps.
This functionality is initialized in `runtime/bin/main_impl.cc` /
`runtime/bin/crashpad.cc`. That may start a subprocess. If that
subprocess has the tempdir as working directory (or inherit handles
referring to it / subdirs/subfiles) it may prevent it from being
deleted.
Adding '--suppress-core-dump' to the Dart process invocations prevents
this.

Implicitly induced noSuchMethod forwarders cannot eliminate primitive
equality: They are not generated at all if they would override an
explicit member declaration (here: `Object.hashCode` and `Object.[]`).
Hence, the classes `Secret...` that we used to have (which were intended
to do just that) were simply compile-time errors, and hence those
classes and the locations where they were used are being removed in
this CL.

Some artifacts are .exe instead of .bat.
Library uris with file schemes use the Uri.path (using forward slashes
on Windows), so the tests emitting native asset mappings should use
Uri.path as well. (Not Uri.toFilePath() which uses backwards slashes.)
The paths of the dynamic libraries in the assets should use the
toFilePath(), as these are passed to the system API which expects
correct paths.
The Platform.script Uri has a path with file:///C: and back slashes.
The uri RFC does not support back slashes, and our ResolveUri does
neither. So for Windows we replace backslashes with forward slashes.

This CL introduces `VarArgs` to `NativeFunction` signatures. The
`VarArgs` type takes a single type argument. This type argument is a
subtype of `NativeType` if there is a single variadic argument, and a
record with native types if there are multiple variadic arguments.
For example:
`NativeFunction<Void Function(Pointer<Char>, VarArgs<(Int32,Int32)>)>`
for calling refering to a `printf` binding with two `int32_t` arguments
passed as variadic arguments.
The logic of the native calling conventions are detailed in
https://dart-review.googlesource.com/c/sdk/+/278342.
Here we explain how this influences the FFI pipeline.
First, now that `VarArgs` is part of signatures, we have to unwrap
that when with the C types in the CFE transform and checking (analyzer
is in a separate CL), and also in the marshaller when looking up the
C type of arguments.
Second, we have to deal with `BothNativeLocations`. On windows x64,
floating point arguments must be passed both in FPU _and_ CPU
registers. For FFI calls, we solve this in the argument moves by just
copying to both locations. For FFI callbacks, we just take the FPU
register location (which avoids an extra bitcast).
Third, on System-V, we have to pass an upper bound of the number of
XMM registers used in AL. This means we instead RAX, we use R13 for the
target address. For variadic calls, we always pass 8 in AL as the valid
upper bound. We could consider passing the actual number of XMM
registers used.
We keep using RAX as default register for the function address on non-
variadic calls, because changing to R13 (the first free) register
creates more spilling in leaf calls. R13 is callee-saved while RAX is
not, so using R13 instead of RAX causes us to have to spill the value
from RAX on leaf calls.
Fourth, on both x64 and RISC-V, we pass floats in integer locations.
`EmitNativeMove` has been modified to deal with this, so that we do not
have to insert more `BitCastInstr`s.
The tests are generated by a test generator: `tests/ffi/generator/`.
The formatter doesn't support records yet, so the tests are not properly
formatted.
