5b0070ac0b Start adding register checking 
I'm now realizing we need to simulate loads, or else these will all be wrong

3f2820646d More testbench setup work 
- Copy bare-bones testbench from E85
   - have testbench instantiate a wallypipelinedhart so we can simulate memory/peripherals easier
 - Create .gitignore for vsim files
 - Make PC reset a macro, change to 0x1000 to conform to the bootloader

I don't know a good way to put the linux register trace file we're generating on git,
since its both nontrivial to make and way to big to keep in a git repo

for now it lives in /mnt/scratch/riscv_testbench/
