This makes the following improvements. For `SHT_GNU_versym`: * yaml2obj: set `sh_link` to index of `.dynsym` section automatically. For `SHT_GNU_verdef`: * yaml2obj: set `sh_link` to index of `.dynstr` section automatically. * yaml2obj: set `sh_info` field automatically. * obj2yaml: don't dump the `Info` field when its value matches the number of version definitions. For `SHT_GNU_verneed`: * yaml2obj: set `sh_link` to index of `.dynstr` section automatically. * yaml2obj: set `sh_info` field automatically. * obj2yaml: don't dump the `Info` field when its value matches the number of version dependencies. Also, simplifies few test cases. Differential revision: https://reviews.llvm.org/D94956
