This is https://bugs.llvm.org/show_bug.cgi?id=40009, llvm-objdump does not demangle the symbols when prints symbol table and/or relocations. Patch teaches it to do that.

## Check we demangle symbols when printing symbol table.
# CHECK: SYMBOL TABLE:
[llvm-objdump] --syms: print st_size as "%016" PRIx64 instead of "%08" PRIx64 for 64-bit objects This is GNU objdump's behavior and it is reasonable to match. Reviewed By: grimar Differential Revision: https://reviews.llvm.org/D75588

[llvm-objdump] Further rearrange llvm-objdump sections for compatability Summary: rL371826 rearranged some output from llvm-objdump for GNU objdump compatability, but there still seem to be some more. I think this rearrangement is a little closer. Overview of the ordering which matches GNU objdump: * Archive headers * File headers * Section headers * Symbol table * Dwarf debugging * Relocations (if `--disassemble` is not used) * Section contents * Disassembly Reviewers: jhenderson, justice_adams, grimar, ychen, espindola Reviewed By: jhenderson Subscribers: aprantl, emaste, arichardson, jrtc27, atanasyan, seiya, llvm-commits, MaskRay Tags: #llvm Differential Revision: https://reviews.llvm.org/D68066 llvm-svn: 373671

[llvm-objdump] Print relocation addends in hexadecimal Summary: Matches GNU objdump.

[llvm-objdump] -d: print `00000000 <foo>:` instead of `00000000 foo:` The new behavior matches GNU objdump. A pair of angle brackets makes tests slightly easier. `.foo:` is not unique and thus cannot be used in a `CHECK-LABEL:` directive. Without `-LABEL`, the CHECK line can match the `Disassembly of section` line and causes the next `CHECK-NEXT:` to fail. ``` Disassembly of section .foo: 0000000000001634 .foo: ``` Bdragon: <> has metalinguistic connotation. it just "feels right" Reviewed By: rupprecht Differential Revision: https://reviews.llvm.org/D75713

# INLINE: <foo()>:
[llvm-objdump] Demangle C++ Symbols in branch and call targets Currently C++ symbols are demangled in the symbol table as well as in the disassembly and relocations. This patch adds demangling of C++ symbols in targets of calls and branches making it easier to decipher control flow in disassembly. This also matches up with GNUobjdump's behavior Reviewed By: MaskRay Differential Revision: https://reviews.llvm.org/D77957
