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:
Instead of a whitelist and blacklist and default issue types and default
blacklist and filtering, consider a simpler semantics where
1. checkers can be individually turned on or off on the command line
2. most checkers are on by default
3. `--no-filtering` turns all issue types on, but they can then be turned off again by further arguments
This provides a more flexible CLI and is similar to other options in the infer
CLI, where "global" behaviour is generally avoided.
Dynamically created checkers (eg, AL linters) cause some complications in the
implementation but I think the semantics is still clear.
Also change the name of the option to mention "issue types" instead of
"checks", since the latter can be confused with "checkers".

Summary:
The `-index-store-path` argument does not exist in Clang 5.0 and it gets discarded without any error message. The problem is that its argument, a folder, is not discarded, and Clang considers it as a source file. This leads to the following errors:
- `cannot specify -o when generating multiple output files` (this happens if a `-o` argument is passed)
- `error reading '<PATH>'` (this can be observed when running the "normalized" version of the clang command, generated via the -### flag)
This weird case can be observed when `-index-store-path` is passed in a sequence like the following: `-x c -index-store-path <PATH> -c`.
With this change, we remove the `index-store-path` option, and its argument, from the original clang command.

Summary:
This diff tries to achieve the followings: if we have the following C++ codes:
```
bool foo(int x, int y) {
return &x == &y;
}
```
We want the C++ frontend to emit Sil as if the input is written as
```
bool foo(int x, int y) {
if (&x == &y) return 1; else return 0;
}
```
This matches the behavior of our Java frontend.
The reason why we prefer an explicit branch is that it will force the backend to eagerly produce two different specs for `foo`. Without the explicit branch, for the above example the backend would produce one spec with `return = (&x == &y)` as the post condition, which is not ideal because (1) we don't want local variables to escape to the function summary, and (2) with the knowledge that no two local variables may alias each other, the backend could actually determines that `&x == &y` is always false, emitting a more precise postcondition `return = 0`. This is not possible if we do not eagerly resolve the comparison expression.

atomic so the file should not get garbled by concurrent writes. To get the

infer-out/log, then `grep ^[<PID>] infer-out/log`.
Introduce 3 log levels for debug output and command-line options to set them
for various categories individually.

`SourceFile.invalid` is still used in too many places to actually remove it, often as a dummy initial value that never gets used, but sometimes as an actual value... Worse, we cannot fail on all operations on `SourceFile.Invalid` yet: the `SourceFile.to_string` method is used in too many places where it could get `SourceFile.Invalid` as argument. It's easy to see where it's used by making it raise in the code, then running the tests. This results in spaghetti backtraces that are hard to trace back to a root cause.

Summary:
Read template arguments from the AST and if argument is a type, translate it into Sil type. Then, save this information into procname.
There is one ugly change - linters now may populate tenv (it's not saved anytwhere though)

Summary:
It used to be string which:
1. Doesn't have enough information for parametric models
2. Doesn't have good type
Changing this blows up in clang frontend, but I think it's for the better

Summary: procnames will depend on Typ.t soon and we need to go from `type_ptr` to `Typ.t` when creating procnames. `CType_decl` does this translation it can't depend on `mk_procname_` functions.
