synth_intel_alm: alternative synthesis for Intel FPGAs By operating at a layer of abstraction over the rather clumsy Intel primitives, we can avoid special hacks like `dffinit -highlow` in favour of simple techmapping. This also makes the primitives much easier to manipulate, and more descriptive (no more cyclonev_lcell_comb to mean anything from a LUT2 to a LUT6).

intel_alm: direct LUTRAM cell instantiation By instantiating the LUTRAM cell directly, we avoid a trip through altsyncram, which speeds up Quartus synthesis time. This also gives a little more flexibility, as Yosys can build RAMs out of individual 32x1 LUTRAM cells. While working on this, I discovered that the mem_init0 parameter of <family>_mlab_cell gets ignored by Quartus.
