976494a8ff Fixed Tandem-Verification trace generation issue re. MSTATUS on CSRRx instructions that write to FCSR.
When a CSRRx instruction writes to FCSR/FFLAGS/FRM, the CPU also
changes MSTATUS.FS and, by implication, MSTATUS.SD because the
floating point state has become "dirty".  Tandem Verification
trace-generation was not reporting this update.
