ipa-param-manip: Be careful about a reallocating hash_map
PR 103449 revealed that when I was storing result of one hash_map
lookup into another entry in the hash_map, I was still accessing the
entry in the table, which meanwhile could get reallocated, making the
accesses invalid-after-free.
Fixed with the following, which also simplifies the return statement
which must have been true even now.

(ipa_param_body_adjustments::prepare_debug_expressions): Be
careful about hash_map reallocating itself. Simpify a return
which always returns true.
