objtool: Support Clang non-section symbols in ORC dump
Historically, the relocation symbols for ORC entries have only been section symbols: .text+0: sp:sp+8 bp:(und) type:call end:0 However, the Clang assembler is aggressive about stripping section symbols. In that case we will need to use function symbols: freezing_slow_path+0: sp:sp+8 bp:(und) type:call end:0 In preparation for the generation of such entries in "objtool orc generate", add support for reading them in "objtool orc dump".
