representing the module import rather than making the module immediately
visible. This serves two goals:
* It avoids making declarations in the module visible prematurely, if we
walk past the #include during a tentative parse, for instance, and
* It gives a diagnostic (although, admittedly, not a very nice one) if
a header with a corresponding module is included anywhere other than
at the top level.

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.

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.

where we didn't. Extend our constant evaluation for __builtin_strlen to handle
any constant array of chars, not just string literals, to match.

template, that member has a dependent type (even if we can see the definition
of the member of the primary template), because the array size could change in
a member specialization.

This patch tests introduces a proper codegen test in place of the
"codegen no longer crashes" test introduced in r193664. The test is also
moved from layout to CodeGenCXX.

This options accepts a path to a directory, collects the filenames of the files
it contains, and the migrator will only modify files with the same filename.

Also refine test case to capture the intention of this suppression. Essentially
some developers use __bridge_transfer as if it were a safe CFRelease.

bit fields of zero size. Warnings are generated in C++ mode and if
only such type is defined inside extern "C" block.
The patch fixed PR5065.

This patch disables aliasing (and rauw) of derived dtors to base dtors at -O0.
This optimization can have a negative impact on the debug quality.
This was a latent bug for some time with local classes, but got noticed when it
was generalized and broke gdb's destrprint.exp.

We already have builtins that are only available in GNU mode, so this
mirrors that.
