These tests are likely missing %PrepareFunctionForOptimization
annotation of lambdas. Thus lambdas are no longer inlined and
%DeoptimizeNow does nothing, while the entire point of these tests is
to test deoptimization paths.
Disabling lazy feedback allocation is a quick fix to restore coverage
until we can land a more complete fix (for details see the linked
bug).

between the load of the receiver map and the call to the builtin.
The introduction of a map check allows us to be more permissive.
