target-mips: Fix seg fault for LUI when MIPS_DEBUG_DISAS==1.

The call to gen_logic_imm for OPC_LUI passes -1 for rs. This
causes the MIPS_DEBUG statement to seg fault due to the deference
of regnames[rs]. This patch fixes that.

target-mips: fix TLBR wrt SEGMask

Like r4k_map_address(), r4k_helper_tlbp() should use SEGMask to mask the
address.

target-mips: don't flush extra TLB on permissions upgrade

If the guest uses a TLBWI instruction for upgrading permissions, we
don't need to flush the extra TLBs. This improve boot time performance
by about 10%.

target-mips: don't use local temps for store conditional

Store conditional operations only need local temps in user mode. Fix
the code to use temp local only in user mode, this spares two memory
stores in system mode.

At the same time remove a wrong a wrong copied & pasted comment,...

target-mips: optimize ddiv/ddivu/div/divu with movcond

The result of a division by 0, or a division of INT_MIN by -1 in the
signed case, is unpredictable. Just replace 0 by 1 in that case so that
it doesn't trigger a floating point exception on the host....

target-mips: use deposit instead of hardcoded version

Use the deposit op instead of and hardcoded bit field insertion. It
allows the host to emit the corresponding instruction if available.

At the same time remove the (lsb > msb) test. The MIPS64R2 instruction...
