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)

for line in sys.stdin:
sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line))

; Check to make sure the tail-call return at the end doesn't use a
|
|
; callee-saved register. Register hinting from t2LDRDri was getting this
|
|
; wrong. The intervening call will force allocation to try a high register
|
|
; first, so the hint will attempt to fire, but must be rejected due to
|
|
; not being in the allocation order for the tcGPR register class.
|
|
; The machine instruction verifier will make sure that all actually worked
|
|
; out the way it's supposed to.
