Except that does not work since register_operand checks the mode ...
and then we fail to match:
```
(insn 46 45 47 2 (parallel [
(set (reg:V4SI 148)
(unspec:V4SI [
(mem/c:V2x16QI (reg:DI 147) [0 +0 S32 A128])
] UNSPEC_LDP_FST))
(set (reg:V4SI 149)
(unspec:V4SI [
(mem/c:V2x16QI (reg:DI 147) [0 +0 S32 A128])
] UNSPEC_LDP_SND))
]) "../../../libgcc/libgcov-interface.c":211:2 -1
(nil))
```
Because we only define the load_pair_16 for TImode and TImode != V4SImode here
...
So Back to changing it to only test for reg and subreg of a reg then.
