GETLMEMBASE : Get Local Memory Base Pointer

SPA 5.0:
        GETLMEMBASE   Rd   {&req_6}   {&rdN}   {&wrN}   {?sched}   ;   // Rd is a 64 bit vector2 register.   

GETLMEMBASE allows a thread to read back the per warp LMEMBASE state into a 64-bit Rd register.

The state read back indicates whether the warp is using the default hardware generated (based on class methods) local memory backing store, or a software managed (allocated) backing store.

The virtual address of the backing store (whether hardware or software managed) is also returned.
