cleanup: moved cbmbasic and apple1basic demos into subdirectories
...
* also changed "clang" to "cc"
* enabled optimizations for 64 bit (it's 10 years later!)
* updated README to reflect CPU speed in 2020 (5x faster than 2014!)
* added benchmarking instructions to README

malloc'ed all state instead of having a gigantic struct
...
state_t is now 208 bytes on x86_64 instead of 26 MB. Startup is a little slower though because of ~7000 malloc calls.

The state pointer is no longer global, but passed down to every function.
...
...and surprisingly, it's not any slower. if anything, it's 1% faster.

optimizations (~25%) and cleanup
...
Optimizations:
1. When a transistor is turned on, only add one of the nodes it
controls to listout, otherwise group calculation would be done twice
for this group. This simplifies recalcNodeList(). (This required
the following change: Instead of adding the nodes that control
transistors that have changed to listout, put the nodes that are
switched by transistors on listout.)
2. The group value is calculated while collecting nodes, and the enum
group_contains_value makes sure we don't check for weaker value
indicators than have already been established.
3. listout is now a set, no node will be visited twice for group
calculation, within one interation.
4. When setting input pins of the package to a value, only recalc the
node if it actually changes.
5. Toggling a transistor is done by assigning it the group value
instead of the inverse of its value.
Cleanup:
* Merge the concept of listin with the concept of nodes that change
from the outside and trigger a recalc.
