positives resulting from inlining, particularly inlining of generic,
defensive C++ methods that live in header files. The suppression is

from, and it turns out that the source of the null pointer was an inlined
function call.

This change brings the number of bug reports in LLVM from ~1500 down to
around ~300, a much more manageable number. Yes, some true positives may
be hidden as well, but from what I looked at the vast majority of silenced
reports are false positives, and many of the true issues found by the

[analyzer] Better path notes for null pointers passed as arguments.

Rather than saying "Null pointer value stored to 'foo'", we now say
"Passing null pointer value via Nth parameter 'foo'", which is much better.
The note is also now on the argument expression as well, rather than the
entire call.

This paves the way for continuing to track arguments back to their sources.
