-----------
Parse all DWARF source files in DwarfWalker::buildSrcFiles (#1515)
>From 2.6.4.16 of the DWARF5 standard
Prior to DWARF Version 5, the current compilation file name was not
represented in the file_names field. In DWARF Version 5, the current
compilation file name is explicitly present and has index 0. This is
needed to support the common practice of stripping all but the line
number sections (.debug_line and .debug_line_str) from an executable.
However, libdw takes care of this in dwarf_getsrcfiles.
Fixes a major bug where we produce no function parameter information
when there is only one CU in a binary because
DwarfWalker::parseFormalParam requires line information.
Fixes #1156
