Summary:
"Running as clang" was its own infer subcommand. That's not terribly good
because it makes it hard to specify another subcommand, and in particular it
broke the `compile` subcommand in some integrations because "running as clang"
would always do capture. The cmake tests required to run with `--keep-going`
because of this.
Instead of having its own fake subcommand, simply add a new boolean in the
config for "infer runs as clang", as we do for javac already (used in the mvn
integration).
Also make logging of the environment better.

Summary:
The behaviour of infer was observed to be different in 4.04.2 vs (4.05.0 or
4.04.2+flambda). Investigating further, the behaviour is also different in byte
vs native versions of infer under 4.04.2. Looking at the Changelog of 4.05.0
(thanks mbouaziz), there are fixes for inconsistent behaviours between byte
and native relative to evaluation order.
Lots of debugging later, this 1 line patch is born. Also use `List.concat_map`
instead of re-implementing it.

Summary:
We supported globals as sources before, but we did so by allowing ClangTrace etc. to match against any access path in the footprint of the trace.
This is very powerful/flexible, but it's ultimately not a good idea because it leads to traces that are hard to read.
This is because a footprint source doesn't have any information about its provenance: we might know that the value came from a global, but we don't know where the read occurred.
The mechanism for handling procedure calls as sources already knows how to solve this problem.
This diff implements globals as sources as a special case of procedure call sources instead.
This will give us much nicer traces with full provenance of the read from the global.

Summary:
Installing with `opam pin` risks upgrading a lot of package in the current
switch, which is very slow. It's also wasted work since we'll install back
their older versions afterwards with `opam lock`. Moreover, that second step
can now fail if javalib needs to be recompiled (which it seems it does),
because we delete the javalib sources after having pinned them.
Solution: 1. do not install javalib at `opam pin` time, and 2. do not remove its source tree after pinning.
