Not documented hardware multiplier

[zhaoleicpp]

I compiled using Code Composer Studio 6.0.1
and disasm with IAR 5.50.2, got:
01ABAC 4C82 04D0 mov.w R12,&MPY32L
01ABB0 4D82 04D2 mov.w R13,&MPY32H
01ABB4 4E82 04E0 mov.w R14,&OP2L
01ABB8 4F82 04E2 mov.w R15,&OP2H
01ABBC 421C 04E4 mov.w &RES0,R12
01ABC0 421D 04E6 mov.w &RES1,R13
It is a new hardware multiplier not simio_hwmult.c.
It may be 32bit*32bit=64bit.
