Also relands the followup CLs:
"Perform non-covariant checks when dynamically invoking callables."
"Use AreValidArguments so that names are checked as well."
Original description of first CL:
This change only affects compilation when running in non-precompiled
mode with --no-lazy-dispatchers enabled.
Instead of always compiling in non-covariant checks, even for closures
not called dynamically, remove the non-covariant checks from the closure
and instead do the non-covariant checks for dynamic calls during the
NoSuchMethodForCallStub fallback by calling
Function::DoArgumentTypesMatch.
Adds two overloads for Function::DoArgumentTypesMatch, one which takes a
function type argument vector and one which takes neither an
instantiator type argument vector or a function type argument vector.
For the versions that are not explicitly passed a type argument vector,
an appropriate one is constructed using the arguments. If there is not
enough information in the arguments, then we fall back to assuming the
empty type argument vector for the instantiator case and instantiating
to bounds in the function type argument case.
Fixes Function::DoArgumentTypesMatch to handle generic functions and to
check arguments appropriately according to the active null safety mode.
For generic functions, the provided or resulting function type vector
has non-covariant checks performed against the type parameter bounds.
This change uncovered one test that was incorrectly passing in strong
mode, see https://github.com/dart-lang/sdk/issues/42688 for details.
Original description of second CL:
The VM only does this when the callable function does not expect dynamic
invocations. Otherwise, performing the checks would be redundant, as the
function body already contains the appropriate non-covariant checks.
Third CL had no additional description.
