symbiflow: changed toolchain command names in Makefile

build/lattice/trellis: set default spimode to None (--spimode not passed to ecppack) as default instead of fast-read.

Using fast-read as default prevent loading the .bit via JTAG (see #589).

trellis: Add option to select SPI mode.

This allows a significant speedup when booting large bitstreams on ECP5
boards that support dual or quad SPI operation.

mor1kx: Do not generate the ror instruction

The mor1kx core does not support `l.ror` instruction
by default, but gcc/clang flags allowed the
compiler to generate it.

cpu: add a few missing GCC toolchains

This names are used by Arch Linux for eg.

Memtest/memspeed improvements

Otherwise we have at least an extra addition in the loop
which squews the result compared to the read loop.

Just create a local clk_domain from clk signal.

The move to libbase reverted the type of the pointer
from long to int.

In a couple of places, memtest uses %x to print a pointer which
is illegal (and could be problematic on 64-bit). Use %p instead.

Additionally, use %ld when printing longs
