Summary:
Currenlty the cost issue is printed at the first node of a function, which is usually the first
statment of the function. This may give a wrong impression that the cost of the statement is
changed.
This diff re-locate where to print issues with heuristics. Going backward from the first node
lines, it looks up a line satisfying,
1. A line should start with <fname> or should include " <fname>".
2. The <fname> found in 1 should be followed by a space, '<', '(', or end of line.

Summary:
`JavaSplitName` is used to represent Java types (in `Procname` in particular). The type itself is a pair of string (an optional package qualifier) and a "type name" (the quotes are there because it may contain array qualifiers).
For example `java.lang.Object[][]` should be represented as
```
{package=Some "java.lang"; typename="Object[][]"}
```
The constructor `make` was misused to construct instead types such as
```
{package=None; typename="java.lang.Object[][]"}`
```
This is evident when we print the return type of a `Procname` non-verbosely (the default), but we still see the package qualifier.
Obviously this is not just a pretty-printing bug, the values were themselves wrong.
The fix is to use the `of_string` constructor which will parse the package and separate it correctly. Another bug (in response to this one) had to be fixed in `Procname.is_vararg` to maintain behaviour in Nullsafe and Quandary.

Summary:
Old versions of sawja/javalib got the line numbers slightly wrong. The workaround was to do a regexp search in the source file for the right line.
My understanding is that this is no longer necessary. This diff removes it.

Summary: In SIL, Java's array member is a pointer to an array, while C++'s is the array itself. This diff differentiate them in evaluating abstract locations.

Summary:
This will allow to get the numerical results for Cost, Hoisting, Purity without the Inferbo issues.
For now, I still forced Inferbo issues for Cost and Purity to avoid lots of changes in tests, that will go away soon.

Summary:
Goal of the stack: deprecate the `--analyzer` option in favour of turning
individual features on and off. This option is a mess: some of the options are
now subcommands (compile, capture), others are aliases (infer and checkers),
and they can all be replicated using some straightforward combination of other
options.
This diff: stop using `--analyzer` in tests. It's mostly `checkers` everywhere,
which is already the default. `linters` becomes `--no-capture --linters-only`.
`infer` is supposed to be `checkers` already. `crashcontext` is
`--crashcontext-only`.
