Andrew Waterman 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.

Andrew Waterman 52fc34a138 Chisel3: bulk connect is not commutative
We haven't decided if this is a FIRRTL limitation that we should relax,
or a backwards incompatibility we're forced to live with.  Should make
for lively debate.
