Support for inline assembler & `goto` instructions in inline assembler

[WernerDrasche]

Depends on https://github.com/goblint/cil/pull/161.

---

The tests with annotations will come in very few days. We are sorry for this (right now still) unpolished state.

Changes in goblint-cil:

• asm is now statement
• goto asm is parsed

Changes in analyzer: all changes are switched off by default and can be turned on by --disable asm_is_nop

• CFG now has edges to labels referenced in goto asm label list
• base emits new Invalidate {lvals} event (with the lvals of the out-clobbers)
• We tried to the best of our abilities to handle this event and/or add asm transfer functions in the analyses where necessary

Before we can continue reviewing, can you please merge master into this and temporarily pin goblint-cil in the opam file such that the CI can run?

[WernerDrasche]

I don't know how to tell this to use our goblint-cil repo (the pinning and downgrading procedure as described on your website only works locally I think) Edit: I think it should work now.

Edit: I think it should work now.

The pin should be repeated in the goblint.opam.locked file (for the locked jobs that run on every commit), other than that you found the right way to do it.

This message from github about the semgrep jobs confuses me: I only approved the run as usual. Not sure what this is about...

What shall we do in cfgTools.ml if we can't access GobConfig?

What shall we do in cfgTools.ml if we can't access GobConfig?

What does that mean? CfgTools opens GobConfig and uses get_bool in a bunch of places just fine.
