Alessandro Arzilli b65882a588 proc: ignore DW_TAG_inlined_subroutine entries without abstract origin (#1637) ...

GCC produces DW_TAG_inlined_subroutine entries without a
DW_AT_abstract_origin attribute.
From the bug report:

 <1><1fe6c7c>: Abbrev Number: 41 (DW_TAG_subprogram)
    <1fe6c7d>   DW_AT_external    : 1
    <1fe6c7d>   DW_AT_name        : (indirect string, offset: 0x485814): MultiGetImpl
    (omissis)
 <2><1fe6c9e>: Abbrev Number: 65 (DW_TAG_inlined_subroutine)
    <1fe6c9f>   DW_AT_low_pc      : 0x311023a
    <1fe6ca7>   DW_AT_high_pc     : 0x5
    <1fe6caf>   DW_AT_call_file   : 10
    <1fe6cb0>   DW_AT_call_line   : 1690
 <2><1fe6cb2>: Abbrev Number: 20 (DW_TAG_inlined_subroutine)
    <1fe6cb3>   DW_AT_abstract_origin: <0x1ffb534>
    <1fe6cb7>   DW_AT_entry_pc    : 0x311023f
    <1fe6cbf>   DW_AT_ranges      : 0xe9bf20
    <1fe6cc3>   DW_AT_call_file   : 10
    <1fe6cc4>   DW_AT_call_line   : 1690

Inlined subroutine at 1fe6c9e doesn't have abstract origin, a name or a
declaration location. It's unclear whether this is in-standard and what
it even means.

Let's ignore it.

Fixes #1636
