  Changed paths:
    M clang/lib/Analysis/UnsafeBufferUsage.cpp
    M clang/test/SemaCXX/warn-unsafe-buffer-usage.cpp

  Log Message:
  -----------
  [-Wunsafe-buffer-usage] Add a new `forEachDescendant` matcher that skips callable declarations

Note this is a change local to -Wunsafe-buffer-usage checks.

Add a new matcher `forEveryDescendant` that recursively matches
descendants of a `Stmt` but skips nested callable definitions.  This
matcher has same effect as using `forEachDescendant` and skipping
`forCallable` explicitly but does not require the AST construction to be
complete.
