Some small memory improvements. CPU seems to be a wash. Seems about as I expected.

wall-time shows some potential improvements, but it might well be within the noise margin (which is quite high for wall-time).

I suspect we should merge this though -- it seems like a bitset is going to behave better as we scale up (e.g., with hundreds of locals), at least from a memory usage perspective.

r=me if you feel similarly on the changes (including if you fix my nit along the way)

Chocolatey timed out waiting for the command to finish. The timeout 
 specified (or the default value) was '2700' seconds. Perhaps try a 
 higher `--execution-timeout`? See `choco -h` for details.
The install of msys2 was NOT successful.
Error while running 'C:\ProgramData\chocolatey\lib\msys2\tools\chocolateyinstall.ps1'.
 See log for details.

Chocolatey installed 0/1 packages. 1 packages failed.
 See the log for details (C:\ProgramData\chocolatey\logs\chocolatey.log).
