[clang] Short-circuit trivial constructors when evaluating arrays
VisitCXXConstructExpr() will later do something similar, but for large
arrays, we should try to do it once an not for every element.

[NFC] Remove some boilerplate from SmallVector unit tests
In SmallVector unit test, referring test suite members every time using 'this'
(due to how non-dependent name lookups works) is quite cumbersome and can be improved with aliases.
Some test cases already use this approach, in this change we expand that approach to whole test file.

[Docs] Improve cycle and closed path definitions
Improve the cycle definition, by avoiding usage of not yet defined
or only vaguely defined terminology inside definitions.
More precisely, the existing definition defined "outermost cycles",
and then proceeded to use the term "cycles" for further definitions,
which in turn were used to actually define "cycles".
Now, instead only define "cycles". This does not change the meaning
of a cycle, which depends on the chosen surrounding (subgraph) of a CFG.
Also mention the function CFG in the first definition, because later
later definitions require it anyways.
Also slightly improve the definition of a closed path, by explicitly
requiring the inner nodes to be distinct.

[SCEV] Use context to strengthen flags of BinOps
Sometimes SCEV cannot infer nuw/nsw from something as simple as
```
len in [0, MAX_INT]
...
iv = phi(0, iv.next)
guard(iv <s len)
guard(iv <u len)
iv.next = iv + 1
```
just because flag strenthening only relies on definition and does not use local facts.
This patch adds support for the simplest case: inference of flags of `add(x, constant)`
if we can contextually prove that `x <= max_int - constant`.
In case if it has negative CT impact, we can add an option to switch it off. I woudln't
expect that though.
