Node is missing some FFI functions from base

[Z-snails]

If possible, please include complete self contained source files (for example by uploading to https://gist.github.com) that exhibit the issue in addition to quoting from them here. The smaller the example the better!

Steps to Reproduce

Try to compile various System.* functions with node codegen

Expected Behavior

Works

Observed Behavior

Fails with

Uncaught error: INTERNAL ERROR: No supported backend found in the definition of System.Errno.prim__getErrno. Supported backends: "node","javascript". Backends in definition: "C".

Here's every FFI function in base that's missing a node version if someone wants to implement these:

• [x] Data.Buffer
  • [x] prim__setBits64
  • [x] prim__getBits64
  • [x] stringByteLength

  • [x] prim__clockTimeUtc
  • [x] prim__clockTimeProcess
  • [x] prim__clockTimeThread
  • [x] prim__clockTimeGcCpu
  • [x] prim__clockTimeGcReal
  • [x] prim__osClockValid
  • [x] prim__osClockSecond
  • [x] prim__osClockNanosecond
• [ ] System.Concurrency
  • Not all these can be implemented
• [x] System.Directory
  • [x] prim__openDir
  • [x] prim__closeDir

I just ran into this when attempting to compile idris2 for javascript. In my case it was prim__os that is missing, and I don't see it on the list above. Would you be able to add it?

Ignore me. I see that prim__os isn't supported on JavaScript, and so idris2 can't be compiled for it.

2427 completed Data.Buffer and System.Directory. Let's check those off :)
