Improve block read and checksum speed (#381)
* Cache program buffer writes.
Speeds up flash program by 3%, flash verify by 2%.
Change-Id: I19f8f44f560a1111fa8f4e4fc04ce6de3c94999a
* Remove nop from batch reads.
program @ 22.123 KiB/s, verify @ 47.654 KiB/s (up from program @ 20.287
KiB/s, verify @ 23.148 KiB/s originally).

* Use "algorithm" to compute CRC on RISC-V targets.
Use the C compiler to generate the algorithm code. It's better at
assembly than I am. We need separate RV32 and RV64 binaries to handle
shift instructions. I used the code from gdb (libiberty really) because
it returns the correct result. I'm not sure if the table is worth it
since we do have to save/download/restore more bytes now.
riscv_run_algorithm() now properly saves and reads back all registers
used for parameters. It also doesn't check final_pc if exit_point is 0.
Using gdb means I don't know the exact address where the code will end.
Small target.[ch] change to be able to run algorithms at 64-bit
addresses.
Flashing an arty board now:
