Fixed test cases for medeleg issue 444. Also added a COMPRESSED_SUPPORTED parameter true when C or Zca is supported, and use this to get compressed hardware such as the spill logic and the +2 adder.

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.
