ELF: Handle R_ARM_V4BX correctly in PIC output files. Previously we considered R_ARM_V4BX to be an absolute relocation, which meant that we rejected it in read-only sections in PIC output files. Instead, treat it as a hint relocation so that relocation processing ignores it entirely. Also fix a problem with the test case where it was never being run because it has a .yaml extension and we don't run tests with that extension.

Relocations:
[lib/ObjectYAML] - Make `ELFYAML::Relocation::Offset` optional. Currently `yaml2obj` require `Offset` field in a relocation description. There are many cases when `Offset` is insignificant in a context of a test case. Making `Offset` optional allows to simplify our test cases. This is what this patch does. Also, with this patch `obj2yaml` does not dump a zero offset of a relocation. Differential revision: https://reviews.llvm.org/D75608
