Goal is to be able to compile a return 0; function (including off-thread MIR building), behind a --warp shell flag. That will give us something concrete to improve.

This has just enough code to be able to compile a "return 0;" function,
including off-thread MIR building.
The new builder consists of two parts:
- WarpOracle: runs on the main thread, produces a WarpSnapshot.
- WarpBuilder: can run off-thread, uses the WarpSnapshot to generate MIR.
WarpOracle will make a lot of the optimization decisions (which scripts can be
compiled, which ICs are copied, which functions we want to inline). WarpBuilder
will do 'just' MIR building.
This is an early prototype; the code is expected to change significantly the
coming weeks/months.
Depends on D64012
