arm: [MVE intrinsics] Another fix for moves of tuples (PR target/118131)

Commit r15-6389-g670df03e5294a3 only partially fixed support for moves
of large modes: despite the introduction of V2x* and V4x* modes in
r15-6245-g4f4e13dd235b to support MVE tuples, we still need to support
TI, OI and XI modes, which appear for instance in gcc.dg/pr100887.c.

The problem was noticed when running the testsuite with
-mthumb/-march=armv8.1-m.main+mve.fp+fp.dp/-mtune=cortex-m55/-mfloat-abi=hard/-mfpu=auto
where several tests would ICE in output_move_neon.

gcc/ChangeLog:

	PR target/118131
	* config/arm/arm.h (VALID_MVE_STRUCT_MODE): Accept TI, OI and XI
	modes again.
