David Blaikie 7c9c6ed761 [opaque pointer type] Add textual IR support for explicit type parameter to load instruction
Essentially the same as the GEP change in r230786.

A similar migration script can be used to update test cases, though a few more
test case improvements/changes were required this time around: (r229269-r229278)

; Verify that register pressure heuristics are working in MachineScheduler.
;
; We can further reduce spills in this case with a global register
; pressure heuristic, like sethi-ullman numbers or biasing toward
; scheduled subtrees. However, these heuristics are marginally
; beneficial on x86_64 and exacerbate register pressure in other
; more complex cases.
