[Libre-soc-dev] [RFC] REMAP, SHAPE, complex (full) FFT

[Luke Kenneth Casson Leighton]

the next step here is to get instruction count down.

this involves merging of SVREMAP 32 bit SPR into SVSTATE 32 bit SPR to
make a single y4 bit SPR.

this is quite an intrusive change right across all HDL, simulator, and
unit tests.

it will need to be done in phases.
