Modern gcc is happy to constant evaluate __builtin_strlen in various cases
where we didn't. Extend our constant evaluation for __builtin_strlen to handle
any constant array of chars, not just string literals, to match.

[analyzer] Include bug column numbers in HTML output (in a comment).

This has no effect on user-visible output, but can be used by post-processing
tools that work with the generated HTML, rather than using CmpRuns.py's
interface to work with plists.

Patch by György Orbán!

[analyzer] Silence warnings coming from allocators used by std::basic_string.

This is similar to r194004: because we can't reason about the data structure
invariants of std::basic_string, the analyzer decides it's possible for an
allocator to be used to deallocate the string's inline storage. Just ignore
this by walking up the stack, skipping past methods in classes with
"allocator" in the name, and seeing if we reach std::basic_string that way.

Don't reject dependent range-based for loops in constexpr functions. The loop
variable isn't really uninitialized, it's just not initialized yet.
