Before this change .symtab section was required for SHT_REL[A] section
declarations. yaml2obj automatically defined it in case when YAML document
did not have it.
With this change it is now possible to produce an object that
has a relocation section, but has no symbol table.
It simplifies the code and also it is inline with how we handle Link fields
for another special sections.

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.

This patch removes trivial-object-test.elf-i386,
trivial-object-test.elf-x86-64 and trivial-object-test2.elf-x86-64
precompiled objects from test/Object/Inputs folder.
I adjusted the existent test cases to use YAML instead.

When --section-headers is used, GNU objdump prints both LMA and VMA for sections.
llvm-objdump does not do that what makes it's output be slightly inconsistent.
Patch teaches llvm-objdump to print LMA/VMA for ELF file formats.
The behavior for other formats remains unchanged.

Summary:
This affects what sections are displayed as "DATA" in llvm-objdump.
The other user llvm-size is unaffected.
Before, a "TEXT" section is also "DATA", which seems weird.
The sh_flags condition matches that of bfd's SEC_DATA but the sh_type
condition uses (== SHF_PROGBITS) instead of bfd's (!= SHT_NOBITS).
bfd's SEC_DATA is not appealing as so many sections will be shown as DATA.

flags as binutils objdump but the output is different, not just in format but
also showing different sections. Compare its results against readelf, not
objdump.
