[PATCH] Address FIXME in i386-tdep.c:i386_extract_struct_value_address

We know for sure here that we're not dealing with a cooked register.

Checked in.

        * i386-tdep.c (i386_extract_struct_value_address): Use
        regcache_raw_read_unsigned instead of
        regcache_cooked_read_unsigned since we know that the register
        we're reading isn't a pseudo register.  Rename variable 'val' into
        the more descriptive 'addr'.
