Peter Collingbourne 6708c4a176 Implement diagnostic mode for -fsanitize=cfi*, -fsanitize=cfi-diag.
This causes programs compiled with this flag to print a diagnostic when
a control flow integrity check fails instead of aborting. Diagnostics are
printed using UBSan's runtime library.

The main motivation of this feature over -fsanitize=vptr is fidelity with
the -fsanitize=cfi implementation: the diagnostics are printed under exactly
the same conditions as those which would cause -fsanitize=cfi to abort the
program. This means that the same restrictions apply regarding compiling
all translation units with -fsanitize=cfi, cross-DSO virtual calls are
forbidden, etc.

Peter Collingbourne 9881b78b53 Introduce -fsanitize-trap= flag.
This flag controls whether a given sanitizer traps upon detecting
an error. It currently only supports UBSan. The existing flag
-fsanitize-undefined-trap-on-error has been made an alias of
-fsanitize-trap=undefined.

This change also cleans up some awkward behavior around the combination
of -fsanitize-trap=undefined and -fsanitize=undefined. Previously we
would reject command lines containing the combination of these two flags,
as -fsanitize=vptr is not compatible with trapping. This required the
creation of -fsanitize=undefined-trap, which excluded -fsanitize=vptr
(and -fsanitize=function, but this seems like an oversight).

Now, -fsanitize=undefined is an alias for -fsanitize=undefined-trap,
and if -fsanitize-trap=undefined is specified, we treat -fsanitize=vptr
as an "unsupported" flag, which means that we error out if the flag is
specified explicitly, but implicitly disable it if the flag was implied
by -fsanitize=undefined.

The most general model has fields for the vbptr offset and the vbindex.

referencing an entity from a vbase.

Daniel Jasper ed3f395773 clang-format: [JS] Add a special case for indenting function literals.
Before:
  var func =
      function() {
        doSomething();
      };

After:
  var func =

  };

This is a very narrow special case which fixes most of the discrepency
with what our users do. In the long run, we should try to come up with
a more generic fix for indenting these.

Alexey Samsonov 9170efdc0d [Sanitizers] Provide better diagnostic for sanitizers unsupported for target triple.
Summary:
Introduce ToolChain::getSupportedSanitizers() that would return the set
of sanitizers available on given toolchain. By default, these are
sanitizers which don't necessarily require runtime support (i.e.
set from -fsanitize=undefined-trap).

Sanitizers (ASan, DFSan, TSan, MSan etc.) which cannot function
without runtime library are marked as supported only on platforms
for which we actually build these runtimes.

This would allow more fine-grained checks in the future: for instance,
we have to restrict availability of -fsanitize=vptr to Mac OS 10.9+
(PR23539)

Update test cases accrodingly: add tests for certain unsupported
configurations, remove test cases for -fsanitize=vptr + PS4
integration, as we don't build the runtime for PS4 at the moment.

Test Plan: regression test suite

Summary:
Qualify all types used in AST matcher macros. This makes it possible to
put AST matchers in user code into a namespace other than clang::ast_matchers
and this way prevent ODR violations that could happen when a matcher with the
same name is defined in multiple translation units. Updated comments
accordingly.
