Summary:
First step in writing an analyzer that is meant to run only on Android core library implementation.
This will, when finished, compute the library entrypoints that may lead to a strict mode violation.
The normal analyzer will use those to statically flag strict mode violations in app code.
Strict Mode is an Android debug mode, where doing certain things (like disk read/write or network activity) on the UI thread will raise an exception. We want to statically catch these, as well as indirect versions (the UI thread takes a lock and another thread holding that lock calls a method that would be a strict mode violation).

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.

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`)

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.
