The dynamic map check builtin loads the feedback vector from the
function's frame, therefore it doesn't work if we inline the
function. We don't do inlining on TurboProp so this is fine, but
it was possible to enable dynamic map checks on TurboFan which does.
This change prevents that, and also makes the dynamic map checks flag
specific to TurboProp and no longer an implication, which also allos
it to be switched on the command line independenly of --turboprop.

The TryMigrateInstance should be passed the instance object to migrate,
not the map of the object. Also make the runtime function explicitly
check for JSObjects.
