WIP Move++ move-mv-llvm-compiler with Aptos FE

[jcivlin]

This includes compilation of Aptos added move stdlib (find it under move-mv-llvm-compiler/tests/extern directory).

Code generation may have some problems, but FE passes, we can compile lambda, iterator, inline.

This does not support our old compilation path from the bytecode, since Aptos removed the old api.
It possibly may be restored - Aptos has some new building interfaces. I'm not sure we will need this, but I want to store in the repo as much of working code as I have.

Do not expect our tests "from bytecode" will work. But stdlib-tests does!

This is difficult to evaluate as is, since it is a huge diff that (I think) is copying aptos code into our non-aptos-based tree, creating a hybrid of mainline move and aptos move.

If we are going to switch to an aptos base I might do it like

• first rebase our entire tree off move/main
• then squash our entire diff into one patch
• then rebase that one patch off the move/aptos-main branch
