Summary: We were missing reads of `a` if it was used in void cast, i.e. `(void) a;` This caused dead store false positives: we were not using `exp` that was the result of translating `a`. This diff creates a call to built-in skip function with `exp` as its argument, which causes the analyses to see reads of `exp`.

Summary: Removing an internal error in SIL to HIL translation which I had added before to log how often the particular case was happening. It happens quite often, and I have a task to investigate the issue. Removing it as it spams the analysis output a lot.

These html pages are written by hand, but their target is auto-generated.
I cheated a bit by generating the docs for the current version of infer and not
0.15.0 but they are hopefully very similar.

Summary:
`make doc` will use `jbuilder` (which in turn uses `odoc`) to generate the
documentation for infer's modules. This is useful to browse the APIs of infer
and gives a more discoverable place to host more general documentation about
infer's internals.
Besides the actual plumbing necessary to generate the docs, this diff also
- Moves the various infer/src/*/README.md to index.mld files that make it to the generated docs
- Fixes some doc comments that would anger `ocamldoc`
Closes#435

Summary: The clang distribution uses symlinks in some places, which avoids copying rather large binaries. `make install` was replacing these with actual copies. Try not to be so wasteful anymore.

Summary:
Use the component of the abstract state `events` to report. This set contains reachability facts about blocking calls and lock acquisitions.
The other component, `order`, contained pairs of a reachable event `e'` from an event option with the semantics that if the option is `None` then we have an element that now goes into `events`, and if the option is `Some e` then the element represents a lock acquired and a trace *from* `e` to `e'`
Now, `order` can be simplified to proper pairs of events, without the option.

Change the documentation to refer to (upcoming) binary releases. Update the
scripts to treat .release differently: now we want to build clang and the
plugins even in release mode, as that's just the preparation for the release

Summary:
It's useful to test that the bucket a given error is classified as doesn't
change over time without notice.
This records the bucket for *all* the tests, even though some never produce a
bucket. This is to be on the safe size instead of risking to forget adding the
bucket information when the test changes, or when copy/pasting from a test that
doesn't have buckets to one that does.
The implementation is pretty crude: it greps the beginning of the qualifier
string for a `[bucket]`.
