[AArch64] Reject invalid subregs involving partial SVE modes
When adding partial SVE modes, I'd remembered to handle reloads
in a similar way to full big-endian SVE vectors, but forgot the
just-as-important mode-change rules.

gcc/
* config/aarch64/aarch64.c (aarch64_can_change_mode_class):
Don't allow changes between partial SVE modes and other kinds
of mode. Don't allow changes between two partial SVE modes
if they have different container or element sizes.
gcc/testsuite/
* gcc.target/aarch64/sve/mixed_size_8.c: New test.
