Added ZCA/ZCF/ZCD/ZCB support. Doesn't break regression, but not tested. Need to get tests for Zcb. Draft tests are in riscv-arch-test but not yet committed there

Modified the LSU/IFU and caches to improve critical path. Arty A7 went from 15 to 17Mhz. I believe we can push all the way to 20+Mhz with relatively little effort. Along the way I'm fixing up the scripts build the linux images for the flash card.

Wow. The newest version of Vivado does not like the enums as parameters.
The solution is simple. I changed the type to logic [31:0] and defined macros for the branch predictor types as 32 bit integers.

Got the branch predictor parameterized using Lim's method. Also had to add a global enum included in both cvw.sv and the configs which defines the branch predictor types. This should be synthesizable, but I'll need to double check.
