tccasm: Unify C and asm symbol table

This makes the asm symbols use the same members as the C symbols
for global decls, e.g. using the ELF symbol to hold offset and
section.  That allows us to use only one symbol table for C and
asm symbols and to get rid of hacks to synch between them.

We still need some special handling for symbols that come purely
from asm sources.
