an existing ir for load of a bock variable. This cannot be
done across basic blocks.

70910a6ab6 Optimize ScalarEvolution's SCEVComplexityCompare predicate: don't go 
scrounging through SCEVUnknown contents and SCEVNAryExpr operands;
instead just do a simple deterministic comparison of the precomputed
hash data.

Also, since this is more precise, it eliminates the need for the slow
N^2 duplicate detection code.

a3bba3371a Create new accessors to get arguments for call/invoke instructions. It breaks 
encapsulation to force the users of these classes to know about the internal
data structure of the Operands structure. It also can lead to errors, like in
the MSIL writer.

2f96e9f5c9 Add an extension to avoid an error when a global template has the same name as 
a member template, and you try to call the member template with an explicit
template argument.  See PR7247 

For example, this downgrades the error to a warning in:

template<typename T> struct set{};
struct Value {
    template<typename T>
    void set(T value) {
    }
};
void foo() {
    Value v;
    v.set<double>(3.2);  // Warning here.
}
