Find the name of the inlined function through a DW_AT_specification
The name is not necessarily found in the abstract origin, it can be
in a referred to specification.

If both a name and a DW_AT_specification is found in the abstract origin,
the name will have priority over the name of the specification.
(unclear if that can happen)
