[PATCH 02/10] attribute: split handle_asm_name() from handle_attributes()

[Luc Van Oostenryck <luc.vanoostenryck@gmail.com>]

handle_attributes() handles attributes but also the asm names.
These asm names must occur before the attributes and only once
while the attributes may occur multiple time. Also, these asm
names are not allowed everywhere attributes, only in declarations.

It's maybe handy to process both in the same function but it's
also slightly confusing. So, move the handling of the asm names
in a separate function.
