tcg/mips: Fix SoftTLB comparison on mips backend
The addrl used to compare with SoftTLB entry should be sign-extended
in common case, and it will cause constant failing in SoftTLB
comparisons for the addrl whose address is over 0x80000000 on the
emulation of 32-bit guest on 64-bit host.
This is an important performance bug fix. Spec2000 gzip rate increase
from ~45 to ~140 on Loongson 3A4000 (MIPS compatible platform).
