middle-end/100786 - constant folding from incompatible alias
The following avoids us ICEing doing constant folding from variables
with aliases of different types. The issue appears both in
folding and CCP and FRE can do more fancy stuff to still constant
fold cases where the load is smaller than the initializer so
defer it to there.

values of compatible type to the symbol.
