bfd/COFF: propagate function size when copying/linking ELF objects

While COFF, unlike ELF, doesn't have a generic way to express symbol
size, there is a means to do so for functions. When inputs are ELF,
propagate function sizes, including the fact that a symbol denotes a
function, to the output's symbol table.

Note that this requires hackery (cross-object-format processing) in two
places - when linking, global symbols are entered into a global hash
table, and hence relevant information needs to be updated there in that
case, while otherwise the original symbol structures can be consulted.

For the setting of ->u.syment.n_type the later writing of the field to
literal 0 needs to be dropped from coff_write_alien_symbol(). It was
redundant anyway with an earlier write of the field using C_NUL.
