Summary:
Now that we got rid of dummy nodes used non-dummily (biabduction state, reporting), `pname` don't need to be an option anymore.
Let's save a boxing on all nodes.

Summary:
Using a dummy node here made the whole reporting wrong because it didn't fail getting a `node_key` when reporting issues from checkers not using the biabduction state.
Now that it's fixed, let's fail hard if someone ever tries again.

Summary: No dummy node key, as a consequence the option `--skip-duplicated-types` will have no effect on issues with no node key, i.e. issues reported by non-biabduction non-eradicate checkers.

Summary: We had a special case for fixing false positives on constexpr implicitly captured by lambdas. However, we do not report dead stores on constexpr anymore, hence, do not need the special case anymore. Moreover, the special case was not only capturing constexpr in lambdas, but also any variables which type had `const` (see new test `capture_const_bad` which was not being reported before this diff)

Summary:
It simplifies abstract memory instantiations of function calls. Now it instantiates callee memories by directly evaluating symbol paths, rather than constructing `subst_map`.
main changes are:
- no construction of `subst_map` and `trace_map`
- no symbol table in Inferbo's summary
- no `Symbol_not_found` exception (for when a required symbol was unavailable in `subst_map`)

Summary:
Separate and rename error reporting functions that use the biabduction state.
No checkers should call these functions.

Summary: We report dead store false positives in template arguments when constexpr is used. To remove the false positives, with the expense of some false negatives, we do not report dead stores on constexpr anymore.

Summary:
Lambdas can capture references to locals of the enclosing method as long as
they are not propagated outside the method. However to keep things simple
always allow them to capture locals of the enclosing method at the price of
some false negatives.

Summary:
In SIL, (1) some program variables (e.g., array parameter) are used as pointers to heap addresses and (2) the other program variables (e.g., local array) are used as addresses themselves. So, the values of (1) are retrieved by the `Load` command, while that of (2) are by `Exp.Lvar` expressions directly.
To address them differently, we had managed two maps (`Mem.Stack` and `Mem.Heap`), but which introduced function duplications on abstract memory and increased complexity. This diff merges the two maps, and instead a location set is used for distinguishing two types of abstract locations during analysis.
