Synthesizing if(DeclRefExpr) throw requires cling to be run with rtti.
...
Fix that problem by introducing an indirection - a compiled function that throws.

For now we will only work/check on declarations that are not deserialized.
...
We don't want our null deref checker to deserialize the whole PCH/PCM. We should
come up with an idea to work around it.

Instead of check each load and store instruction, we check the usage of the load instruction. Currently, there are four kinds of instruction that may use a load instruction as its argument: load, store, GEP and call instruction. We instrument these four kinds instruction to check there may be a null pointer dereference.
