Currently when we dump dynamic relocation with use of
DT_RELA/DT_RELASZ/DT_RELAENT tags, we crash when a symbol index
is larger than the number of dynamic symbols or
when there is no dynamic symbol table.

This patch adds test cases and fixes the issues.
It is rebased on top of D73484 <https://reviews.llvm.org/D73484>.
