Remi Bernon eac9a4342e perf symbols: Try reading the symbol table with libbfd
Wine generates PE binaries for its code modules and also generates debug
files in PE or PDB formats, which perf cannot parse either.

Trying to read symbols on non-ELF binaries with libbfd, when supported,
makes it possible for perf to report symbols and annotations for Windows
applications running under Wine.

Because libbfd doesn't provide symbol size (probably because of some
backends not supporting it), we compute it by first sorting the symbols
by addresses and then considering that they are sequential in a given
section.

v3: Also include local and weak bfd symbols and mark them as such, only
    global symbols were previously reported, and that caused a very
    imprecise address to symbol resolution.
