George Rimar 95aae4c59d [ELF] - Do not fail on R_*_NONE relocations when parsing the debug info.
This is https://bugs.llvm.org//show_bug.cgi?id=38919.

Currently, LLD may report "unsupported relocation target while parsing debug info"
when parsing the debug information.

At the same time LLD does that for zeroed R_X86_64_NONE relocations,
which obviously has "invalid" targets.

The nature of R_*_NONE relocation assumes them should be ignored.
This patch teaches LLD to stop reporting the debug information parsing errors for them.

Rafael Espindola 78fad32d83 Make the debug info in some tests more realistic.
Currently lld just parses the .debug_line section assuming that there
is only one compile unit. That assumption is false (PR36793).

I have a patch that changes lld to iterate over the compile units and
parse the portions of the .debug_line they point to (which fixes
PR36793).

A problem is that we will then need a compiler unit pointing to
.debug_line for lld to see it.

It seems like bfd has the same restriction.

This patch updates existing tests to add a minimal compile unit so
that they still work with PR36793 fixed.

Rafael Espindola e10568364e Fix reloc section alignment in test.
This should fix the ubsan bot.

We still have to fix lld to produce a clean error on unaligned reloc
sections.
