Summary:
Introducing a new argument constraint to confine buffer sizes. It is typical in
C APIs that a parameter represents a buffer and another param holds the size of
the buffer (or the size of the data we want to handle from the buffer).

Some checkers may not only depend on language options but also analyzer options.
To make this possible this patch changes the parameter of the shouldRegister*
function to CheckerManager to be able to query the analyzer options when
deciding whether the checker should be registered.

Summary:
This patch introduces a placeholder for representing the dynamic size of
regions. It also moves the `getExtent()` method of `SubRegions` to the
`MemRegionManager` as `getStaticSize()`.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Summary:
This checker verifies if default placement new is provided with pointers
to sufficient storage capacity.
Noncompliant Code Example:
#include <new>
void f() {
short s;
long *lp = ::new (&s) long;
}
Based on SEI CERT rule MEM54-CPP
https://wiki.sei.cmu.edu/confluence/display/cplusplus/MEM54-CPP.+Provide+placement+new+with+properly+aligned+pointe
This patch does not implement checking of the alignment.
