readdwarf3.c (parse_inl_DIE) inlined_subroutine can appear in namespaces
This was broken by commit 75e3ef0f3 "readdwarf3: Skip units without
addresses when looking for inlined functions". Specifically by this
part: "Also use skip_DIE instead of read_DIE when not parsing
(skipping) children"
rustc puts concrete function instances in namespaces (which is
allowed in DWARF since there is no strict separation between type
declarations and program scope entries in a DIE tree), the inline
parser didn't expect this and so skipped any DIE under a namespace
entry. This wasn't an issue before because "skipping" a DIE tree was
done by reading it, so it wasn't actually skipped. But now that we
really skip the DIE (sub)tree (which is faster than actually parsing
it) some entries were missed in the rustc case.
