proposed fix for sccvn

Well, this is patch I am currently testing. At least small part is shared in
between tree-ssa-ccp (probably should go into gimple-fold) and VN.
I am not sure how much of other initializer folding I need to borrow - i.e.
folding of var_decl into its decl_initial, handling of component_refs and such.

Also the tree-ssa-ccp code seems quite incomplette, it won't fold array with
incomplette initializer for example because it won't find the matching item. 
Probably worth to fix.
