This patch tries to resolve problems faced in D68943 and uses some of the code written by Konrad Wilhelm Kleine in that patch. Previously, yaml2obj tool always created a .symtab section. This patch changes that. With it we only create it when have a "Symbols:" tag in the YAML document or when we need to create it because it is used by another section(s). obj2yaml follows the new behavior and does not print "Symbols:" anymore when there is no symbol table.

## TODO (grimar): without the following line (i.e. without an empty symbol table),
|
|
## llvm-objcopy adds an empty .strtab section. It doesn't look correct.
