[BPF] Fix bpf llvm-objdump issues.
Commit https://reviews.llvm.org/D57939 ("[DWARF] Refactor
RelocVisitor and fix computation of SHT_RELA-typed relocation entries)
made a change for relocation resolution when operating
on an object file.
The change unfortunately broke BPF as given SymbolValue (S) and
Addent (A), previously relocation is resolved to
S + A
and after the change, it is resolved to
S
This patch fixed the issue by resolving relocation correctly.
It looks not all relocation resolution reaches here and I did not
trace down exactly when. But I do find if the object file includes
codes in two different ELF sections than default ".text",
the above bug will be triggered.
This patch included a trivial two function source code to
demonstrate this issue. The relocation for .debug_loc is resolved
incorrectly due to this and llvm-objdump cannot display source
annotated assembly.
