ARMv7_CPU.prototype.usat doesn't work

[fkuzume]

in ARMv7_CPU.prototype.usat = function(inst, addr)

var ret = this.unsigned_satq(this.sint32(operand), saturate_to);
The above statement is incorrect.
The following description seems to be correct.

var ret = this.unsigned_satq(bitops.sint32(operand), saturate_to);

I found a problem with another issue.

this.regs[n] = ret;
The above is an incorrect register for the return.

this.regs[d] = ret;
The correct destination register is regs[d].
