Fangrui Song 2682bc3c9d [ELF] Replace error() with errorOrWarn() for the ASSERT command
Summary:
ld.bfd produces an output with --noinhibit-exec when an ASSERT fails.
Use errorOrWarn() so that we can produce an output as well.

An interesting case is that symbol assignments may execute multiple
times, so we probably want to suppress errors for non-final runs.
