2179cb64ae Let isRead be true for store-conditional 
This works around a deadlock bug in the L1 D$, and is arguably true.

0bfb2962a6 Assume coh.isRead returns true for store-conditional 
This requires an uncore update.

e72e5a34b5 Fix storage of SP values in DP registers 
The SFMA was zero-extending the SP value to 65 bits, rather than filling
the upper 32 bits with 1s.  This meant that an FSD + FLD of that register
would not restore the value properly.

Also, minor code cleanup.
