RISC-V: Update parser to use x-register names, add vector and FP instructions, fix tests

- Modified RISC-V parser to use x-register names instead of ABI names
- Added new vector instructions (vsetvli, vle8.v, vse8.v, vfmacc.vv, vfmul.vf)
- Added floating point instructions (fmul.d)
- Added unconditional jump instruction (j)
- Updated tests to match new register naming convention
- Added new RISC-V example files
- Updated .gitignore to exclude test environment and old examples
