7ea118f248 Begin work on simple x64 backend. 
Introduce register allocation, spilling, etc. First implementation
will likely emit textual assembly and use a very bad register allocation
algorithm.

480c5b5e9d Change how labels are recorded. 
Disallow jumping to arbitrary instructions - instead, only allow jumps
to label ids. This will make various transformations and validations
easier since adding or remove instructions does not break jumps.

ef2dfcd7c3 More work on a proof of concept frontend. 
Basic frontend being prototyped in examples/sysir/frontend.janet. Still
a lot of work needs to be done here, and some of this code will
eventually move to C most likely, but this is a good way to better
exercise our backend.

Type inference - at the very least _forward_ inference, is the most
needed change here. While one could do this in the compiler
frontend, doing so in sysir/asm is not so much of an issue. "Inference"
here means inserting "bind" instructions when there is only a single
type that will work correctly.

549ee95f3d Add os/posix-exec (along os/posix-fork) 
Useful for old-style unix daemons, start up scripts, and so on.
Easy to add on top of os/execute.

May want to consider allowing the same IO redirection as os/execute
and os/spawn.

May also want to put both fork and exec behind a config switch since I
suppose some systems may not support them, although I don't know of any
concrete examples.

84ad161f1e Add support for weak references in arrays. 
Also change weak table syntax to not require keyword arguments.

b3a6e25ce0 Add weak references in the form of weak tables. 
Any references exclusively held by a weak table may be collected
without the programmer needing to free references manually. A table
can be setup to have weak keys, weak values, or both.

efbc46c69e Add support for using operators on arrays (and pointers to arrays). 
Allows more expressive yet type checked representation of array
algorithms.
