Summary:
It renames `eval_locs` to `eval_arr` and we use it for getting array block values the given input expressions are pointing to. For example, when given a program variable `x` as an input, `eval_arr` returns array blocks that `x` is pointing to, on the other hand, `eval` returns an abstract location of `x`.

Summary:
This is unused, but the logic for keeping its value up to date was still alive
and kicking.
I don't know that making use of this flag would be easy: we could just use it
in `Ondemand.should_analyze`, but it would be unsound because a procedure might
need to be re-analysed becauese its dependencies have changed. Since there's
not code to deal with that currently I think it's best to remove it and
re-introduce it when we have some idea how to use it.

Utility function that's basically `Logging.progress` but with a more obvious

The `[@deprecated ...]` ensures no uses gets landed, and the `[@warning "-32"]` ensures that it's not a compile error that there are no uses of this function.

Summary:
There's actually a nice separation between IR/, base/, istd/, and the rest of
infer, so they can be made into separate jbuilder libraries so that the
separation remains. This helps make sense of the infer codebase.
Also:
- move everything biabduction-related out of backend/ and into a new
biabduction/ directory. This clarifies the current situation where backend/
contains a mix of analysis-independent code (still there now), and
biabduction-specific code (moved to biabduction/).
- move everything from base/ that is not infer-specific into istd/, e.g. IList.ml
- kill unused `FbTraceCalls`
- A couple of files needed to move around to complete the separation of base/ and IR/

If an aggregate `a` has a field `f` whose type has a constructor (e.g., `std::string`), we translate creating a local aggregate `A { "hi" }` as `string(&(a.f), "hi")`.

Summary:
Infer reads the arguments passed to clang, in particular to filter out some
incompatible clang command-line options. But, infer only understands arguments
in arg files if they are presented one per line. That's usually the case, but
infer itself stores clang arguments from compilation databases all on one line.
This breaks filtering.
This changes the type of compilation database items to a list of arguments, so
that they can be stored one per line when possible.
Also does some cleanup/renamings, and remove trailing `_` from temp file names, eg:
clang_command_.tmp.2b2602.txt -> clang_command.tmp.2b2602.txt
Also, do not escape arguments from arg files when printing them in logs (that
was useless and ugly).
