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.

Summary:
After some testing, it looks like getting the pdesc via
`Ondemand.get_proc_desc` will also load models' proc descs from their
summaries, so this code should not be needed.

Summary:
`Errlog` will merge similar issues (same severity, name, description) reported at the same location, so let's make sure the locaiton is mandatory.
Issues:
- errors happening in `Ondemand` still use the `State` which makes sense only for biabduction and eradicate
- a case of `NullabilitySuggest` didn't have a location, I did my best to patch it but I'm sure the location could be more precise
