Matt Arsenault 8dbeb9256c TTI: Improve default costs for addrspacecast 
For some reason multiple places need to do this, and the variant the
loop unroller and inliner use was not handling it.

Also, introduce a new wrapper to be slightly more precise, since on
AMDGPU some addrspacecasts are free, but not no-ops.
