0xrsydn b535c08313 fix(cpu): accept ARM multiplies whose destination equals Rm 
MUL/MLA with Rd=Rm and long multiplies with RdHi or RdLo equal to Rm returned
UnsupportedInstruction and stopped the machine. The ARM7TDMI reads every
operand before writing the result, so these forms execute normally. R15
operands and RdHi=RdLo remain diagnostics.
