Add RESTORE_CELL to opcode metadata, fix locals() for inlined comprehension cells

Register RESTORE_CELL (opcode 121) in _opcode_metadata.py so
test__opcode's stack_effect check passes.

In locals(), skip cell values when the same name has a set fastlocal
value. This fixes test_closure_with_inline_comprehension where a cell
variable used as an inlined comprehension iteration target should show
the comprehension's value, not the outer cell value.
