You are right, it's not true. But for .set arch=FOO it should be ok, as
it sets arch and isa.

For .set mipsN we lose the hilo_interlocks optimization for SB1 if a
MIPS IV or lower ISA is chosen.

We lose gpr_interlocks optimizations for VR5400, VR5500 with .set mips1.

We lose cop_interlocks optimizations for VR5400, VR5500, SB1 with
.set mips[1-3]

I think dropping the optimization when the ISA level was explicitly
lowered is an improvement. We should probably generally set the arch
to the default value of the .set ISA.
