Fix test msvc-abi-return-indirect-trivial-record.swift for windows aarch64

The test msvc-abi-return-indirect-trivial-record.swift fails on
windows aarch64 because the type of the third argument of
@"??YLoadableIntWrapper@@qeaa?AU0@U0@@z"
(@LoadableIntWrapper::operator+=(LoadableIntWrapper)) is i64 which
differs from i32 for x86_64. Accommodate this as this is how Clang
generates code. See https://godbolt.org/z/G76aMr5M9.
