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

[Mark Kettenis <kettenis at chello dot nl>]

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

Checked in.

from  Mark Kettenis  <kettenis@gnu.org>

	* 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'.
