[vm] Fix ThrowErrorSlowPath-derived instructions (e.g. CheckNull) in JIT mode.

Previously these instructions were not safe to use on JIT, because they
crated catch-entry moves which are not used in JIT.

Now we assign deopt-infos to these slow paths so they can handle exceptions
correctly in JIT.

I considered removing uses of CheckNull in JIT mode, but I did not find a simple
replacement for all the existing uses.

Fixes #35887.
