[analyzer] Suppress bugs whose paths go through the return of a null pointer.

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

12 years ago[analyzer] Allow a BugReport to be marked "invalid" during path generation.

[analyzer] Allow a BugReport to be marked "invalid" during path generation.

This is intended to allow visitors to make decisions about whether a
BugReport is likely a false positive. Currently there are no visitors
making use of this feature, so there are no tests.

When a BugReport is marked invalid, the invalidator must provide a key
that identifies the invaliation (intended to be the visitor type and a
context pointer of some kind). This allows us to reverse the decision
later on. Being able to reverse a decision about invalidation gives us more
flexibility, and allows us to formulate conditions like "this report is
invalid UNLESS the original argument is 'foo'". We can use this to
fine-tune our false-positive suppression (coming soon).
