[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.

[Libomptarget] Deinitialize AMDGPU global state more intentionally
A previous patch made the destruction of the HSA plugin more
deterministic. However, there were still other global values that are not
handled this way. When attempting to call a destructor kernel, the
device would have already been uninitialized and we could not find the
appropriate kernel to call. This is because they were stored in global
containers that had their destructors called already. Merges this global
state into the rest of the info state by putting those global values
inside of the global pointer already allocated and deallocated by the
constructor and destructor. This should allow the AMDGPU plugin to
correctly identify the destructors if we were to run them.
