24cae2cecf CMake: extract bbasm compilation into a function. 
This fully preserves existing functionality, although the `embed` mode
is untested and seems broken.

d214308f5f CMake: reformat for consistency. 
Normalize keywords to:

    if (...)
    elseif (...)
    else()
    endif()

    foreach (...)
    endforeach()

    other(...)

Normalize whitespace to 4 spaces.

582410629b ice40: Don't assert on unknown extra_config bits if they are 0 
Bits are 0 by default anyway, so if they are unknown (because icestorm
is too od) but we want them at 0 ... it's not much of an issue.

49ae495344 ice40: Add support for PLL ICEGATE function 
Technically you can enable it independently on CORE and GLOBAL
output, but this is not exposed in the classic primitive, so
we do the same as icecube2 and enable/disable it for both output
path depending on the argument

f50d4c1ed1 ice40: Support for undriven / unconnected output ports 
If a port specified as output (and thus had a $nextpnr_obuf inserted)
is undriven (const `z` or const `x`), we make sure to not enable
the output driver. Also enable pull-ups if it was requested by the user.

0cf5006e3b ice40: Rework pull-up attribute copy to SB_IO blocks 
We try to copy the attribute only when there is a chance for
the output driver to not be active.

Note that this can _also_ happen when a port is specified as
output but has a TBUF, which the previous code wasn't handling.

We could copy the attribute "all-the-time" but this would
mean if a user specified a `-pullup yes` in the PCF for a
permanently driven output pin, we'd be burning power for
nothing.

df99b4ff6c ice40: Add debugs to isBelLocationValid for SB_IO 
When there is a constraint conflict while placing IOs, the user gets an
error message such as

ERROR: Bel 'X0/Y27/io1' of type 'SB_IO' is not valid for cell 'my_pin' of type 'SB_IO'

While this identifies the problematic cell, it does not explain why
there is a problem. Add some verbose messages to allow users to
determine where the problem is. This can result in something like

Info: Net '$PACKER_VCC_NET' for cell 'my_pin' conflicts with net 'ce' for 'ce_pin'

which provides something actionable.

Correct Not Equal operator implementation in ice40 
I noticed this during my work reimplementing nextpnr, and it seems to be dead and wrong, or at least dead. Either way I think this is what was intended unless anyone can correct me.

86699b42f6 Switch to potentially-sparse net users array

removing a port from a net is no longer an O(n) operation on the number
