    gprofng: 30834 improve disassembly output for call and branch instructions

    This patch makes the gprofng disassembler to emit, e.g.
        call   fprintf@plt [ 0x401060, .-0x49c]
    instead of
        call   0xfffffffffffffb64

    I use bfd_get_synthetic_symtab() to get function names in the .plt section.
    I have not yet modified Elf-reader in gprofng to remove parsing of .symtab
or
    .dynsym sections. But we plan to do it.

            PR gprofng/30834
            * src/Disasm.cc: Show the function name in the call instruction
            and the relative address in the branch instruction. Remove unused
code.
            * src/Disasm.h (map_PC_to_func, get_funcname_in_plt): New
functions.
            * src/Elf.cc: Get function names for the .plt section.
            * src/Elf.h (get_funcname_in_plt, get_bfd_symbols): New functions.
            * src/Stabs.cc: Add pltSym to SymLst. Remove the conversion to
uint32_t.
