[AArch64] Fix ldst-opt of multiple disjunct subregs.
Currently aarch64-ldst-opt will incorrectly rename registers with
multiple disjunct subregisters (e.g. result of LD3). This patch updates
the canRenameUpToDef to bail out if it encounters such a register class
that contains the register to rename.
Fixes PR46105.
