Implement PtrToInt.

[ptersilie]

Since we cast them to zeroextend instructions, we only have to adjust some debug_asserts to make this work.

Requires: ykjit/ykllvm#158

[vext01]

Just need to add one more here for vectors.

[vext01]

Note that due to the order of our ykllvm merges, #1164 will have to go in before this PR. There will be conflicts. Sorry.

[ltratt]

It might only be the ykllvm submodule update that conflicts?

[vext01]

We both changed the "unsupported" ll test. If there isn't a conflict, Lukas will have to rename his LLVM IR variable numbers so they are sequential again :)

[ptersilie]

Here's the vector case. Will do the rebase once the other PRs are in.

[ptersilie]

Can I squash and rebase?

[vext01]

Go ahead.

[ptersilie]

Managed to get out of merge conflict hell. Let's try again.

Ok to squash?

[vext01]

go ahead.

[ptersilie]

Done.
