Improve ptr_derefs_may_alias_p for the case of &STRING_CST
When the first pointer happens to be a pointer to a STRING_CST we
give up too early since the 2nd pointer handling could still end
up with a DECL for example which can disambiguate against a STRING_CST
just fine.
* tree-ssa-alias.cc (ptr_derefs_may_alias_p): If ptr1
points to a constant continue checking ptr2.
