Thomas Weber 8ce06bc6a8 Import most of the forkphorus test suite (#303) 
forkphorus has its own test suite, most of which are regression tests for real bugs in a real compiler so it may be worth testing against.

forkphorus-befunge-eratosthenes and forkphorus-string-functions are probably the most meaningful new test cases; at the very least i wouldn't have needed a new test case in #300 to see changes in snapshots if they were merged

The tests also add coverage for specializations like "delete 1 of list" that somehow weren't in the suite before?

Thomas Weber 3aca9363a3 Optimize jsexecute helpers (#389) 
* replace Number.isNaN -> x !== x (see https://github.com/TurboWarp/scratch-vm/pull/367 for background on this though it matters less than expected)
 * optimize listGet for numbers
 * optimize listReplace for numbers
 * optimize listDelete for first and last items
 * optimize listContains / listIndexOf by hoisting work that would previously happened inside compareEqual many times

Thomas Weber 7aa8930802 Fix incorrect types for sensing_of 
They can return 0 if the sprite does not exist
Fixes https://github.com/TurboWarp/scratch-vm/issues/262
Closes https://github.com/TurboWarp/scratch-vm/pull/325
(this one uses a different fix and has tests)

There are broader issues about compiled sensing_of not handling dynamic
sprite create/delete. We should tackle that later. The other PR wouldn't
really fix this either.
