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)

|
|
; Live range splitting tries to isolate the block containing the first function
|
|
; call, and it is important that the last split point is after the function call
|

; so the return value can spill.
