This test case triggers a conversion for a tuple class
dead $x0 = PseudoVSETVLI killed renamable $x11, 64, implicit-def $vl, implicit-def $vtype
renamable $v0_v1 = PseudoVLSEG2E8_V_M1 killed renamable $x10, $noreg, 3, implicit $vl, implicit $vtype
$v2_v3 = COPY $v0_v1
PseudoVSSEG2E8_V_M1 killed renamable $v2_v3, killed renamable $x12, $noreg, 3, implicit $vl, implicit $vtype
