target/mips/mxu: Avoid overrun in gen_mxu_q8adde()
Coverity reports a potential overruns (CID 1517770):
Overrunning array "mxu_gpr" of 15 8-byte elements at
element index 4294967295 (byte offset 34359738367)
using index "XRb - 1U" (which evaluates to 4294967295).
Add a gen_extract_mxu_gpr() helper similar to
gen_load_mxu_gpr() to safely extract MXU registers.
Fixes: eb79951ab6 ("target/mips/mxu: Add Q8ADDE ... insns")
