Eliminate remaining case of ambiguous context level info

Eliminate remaining case of ambiguous context level info

When generating the scopes in an await-for loop, make sure the scope
of the loop block is a proper sub-range of the block surrounding
the loop.

This eliminates the last case where the compiler generated context
info of the same range, but with contradicting context level info.
