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

proc: add LocationCover method to BinaryInfo ( #1573 )
...
Also fixes findCompileUnitForOffset which was broken in some edge cases
(when looking up an offset inside the last child of the compilation
unit) which don't happen in normal executables (we only look up types, and those
are always direct childs of compile units).

*: Update import name to github.com/go-delve/delve
...
The repository is being switched from the personal account
github.com/derekparker/delve to the organization account
github.com/go-delve/delve. This patch updates imports and docs, while
preserving things which should not be changed such as my name in the
CHANGELOG and in TODO comments.
