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.

I think I've solved the slow down issue. Parameters can't be mixed with cvw_t and other types.

Updated a large number of the source files to use parameters rather than `defines. Based on Lim's work. So far there is no simulation slow down.

Changed DIVN comparison from NF to NF+2. Shouldn't make a difference on our word sizes of XLEN=32/64, NF = 10/23/52) but is more proper in the general case.
