Aske Simon Christensen 68fd2a9d52 [vm/jit] Pessimize type assumption in LoadLocal of covariant parameter. ...

This avoids unsound optimizations that could arise from loading a
parameter before its type had been checked.

Affects only unoptimized code.

Fixes https://github.com/dart-lang/sdk/issues/43464

Some considerations for a cleaner fix are described in
https://github.com/dart-lang/sdk/issues/43654
