build/sim: use -O0 for verilator compilation
...
In most of the case, execution speed is already fast enough with -O0 and
with complex design -O0 is a lost faster to compile than -O3. In the future
we could add a switch to choose which optimization we want.

software/libbase: memcpy: simple, arch-width agnostic implementation
...
Remove optimizations targeted specifically at rv32 architecture,
allowing memcpy to work on all word sizes.
Since this is "only" the BIOS, it is also arguably better to
optimize for size rather than performance, given that control
will be quickly handed over to some other program being loaded.

Simulate a Rocket-based 64-bit LiteX SoC with the following command:
litex/tools/litex_sim.py [--with-sdram] --cpu-type=rocket
NOTE: Synthesizes to FPGA and passes timing at 50MHz on nexys4ddr
(with vivado) and ecp5versa (with yosys/trellis/nextpnr), but at
this time does not yet properly initialize physical on-board DRAM.
On ecp5versa, using '--with-ethernet', up to 97% of the available
TRELLIS_SLICE capacity is utilized.

The previous value -- 0xc0 -- is used by Windows all the time to query
special descriptors. This was causing a conflict when using the USB
bridge on a Windows device.
Change the magic packet from "Vendor: Device" queries to "Vendor:
