Asu dc77563a6a cxxrtl: keep the memory write queue sorted on insertion. 
Strategically inserting the pending memory write in memory::update to keep the
queue sorted allows us to skip the queue sort in memory::commit.

The Minerva SRAM SoC runs ~7% faster as a result.

whitequark 1d5b6ac253 cxxrtl: add an unsupported knob for manipulating clock trees. 
This is quite possibly the worst way to implement this, but it does
work for a subset of well-behaved designs, and can be used to measure
how much performance is lost simulating the inactive edge of a clock.

It should be replaced with a clock tree analyzer generating safe
code once it is clear how should such a thing look like.

whitequark d22a8d157d cxxrtl: add (*cxxrtl.{comb,sync}*) annotations on black box outputs. 
If the annotations are not used, this commit does not alter semantics
at all, other than removing elision of outputs of black box cells.
(Elision of such outputs is expected to be too rare to have any
noticeable benefit, and the implementation was somewhat of a hack.)

The (* cxxrtl.comb *) annotation alters the semantics of the output
of the black box it is applied to such that, if the black box
converges immediately, no additional delta cycle is necessary to
propagate the computed combinatorial value upwards in hierarchy.

The (* cxxrtl.sync *) annotation alters the semantics of the output
of the black box it is applied to such as to remove any uses of
the black box by the wires connected to this output, and break false
feedback arcs arising from conservative modeling of dependencies of
the black box.

Although currently these attributes are only recognized on black
boxes, if separate compilation is added in the future, it could also
emit and consume them.

whitequark 164b0746d2 cxxrtl: s/sync_{wire,type}/edge_{wire,type}/. NFC. 
The attribute for this is called (* cxxrtl.edge *), and there is
a planned attribute (* cxxrtl.sync *) that would cause blackbox
cell outputs to be added to sync defs rather than comb defs.
Rename the edge detector related stuff to avoid confusion.
