This test would previously expect one of the parameters to have
an incorrect DW_AT_location. Stepping through `fun` with a debugger
would then no reflect updates to one of the parameters.
With a recent change to Clang's DeadArgumentEliminationPass
(see `879f5118fc74657e4a5c4eff6810098e1eed75ac`) the generated
DWARF does not contain a location for `parama`, and stepping through
the function with `lldb` works as expected.
