Description Luke Kenneth Casson Leighton 2020-07-21 14:14:51 BST
to save on regfile ports, PC and MSR need to be pased in to
PowerDecode2 (MSR already is), and put into Decode2Execute1Type
then copied into XXX_input_record (CompXXXOpSubset) as appropriate.

this affects branch, trap and spr pipelines.
