[RISCV] Shrink deleted dead ADDI's use if coalesced in RISCVInsertVSETVLI (#166729)
If two vsetvlis are coalesced (or during insertion when a VSETVLIInfo
turns out to be compatible), we may end up with a dead ADDI that we
delete.
Normally these are LIs (addi $x0, imm), but it's possible for the first
operand to be a virtual register. Make sure we shrink the live interval
of it when we remove it to avoid crashes.
Fixes #166613
