e64a4656b3 Teach the private to local about OpImageTexelPointer. 
OpImageTexelPointer acts like a special kind of load.  It is still
safe to change the storage class of a variable used in a
OpImageTexalPointer instruction.

Contributes to #1445.

b86eb6842b Convert private variables to function scope. 
When a private variable is used in a single function, it can be
converted to a function scope variable in that function.  This adds a
pass that does that.  The pass can be enabled using the option
`--private-to-local`.

This transformation allows other transformations to act on these
variables.

Also moved `FindPointerToType` from the inline class to the type manager.
