This adds support for static_assert() (and _Static_assert()) in
@interface/@implementation ivar lists and in @interface method declarations.
It was already supported in @implementation blocks outside of the ivar lists.
The assert AST nodes are added at file scope, matching where other
(non-Objective-C) declarations at @interface / @implementation level go (cf
`allTUVariables`).
Also add a `__has_feature(objc_c_static_assert)` that's true in C11 (and
`__has_extension(objc_c_static_assert)` that's always true) and
`__has_feature(objc_cxx_static_assert)` that's true in C++11 modea fter this
patch, so it's possible to check if this is supported.

This reverts commit r353765. After talking with our c stdlib folks, we decided
to use the existing pass_object_size attribute to implement _FORTIFY_SOURCE
wrappers, like Bionic does (I didn't realize that pass_object_size could be used
for this purpose). Sorry for the flip/flop, and thanks to James Y. Knight for
pointing this out to me.

llvm-svn: 356097
Summary:
Introduces variants of `getText` and `getSourceRange` that extract the source text of an AST node potentially with a trailing token.
Some of the new functions manipulate `CharSourceRange`s, rather than `SourceRange`s, because they document and dynamically enforce their type. So, this revision also updates the corresponding existing FixIt functions to manipulate `CharSourceRange`s. This change is not strictly necessary, but seems like the correct choice, to keep the API self-consistent.
This revision is the first in a series intended to improve the abstractions available to users for writing source-to-source transformations. A full discussion of the end goal can be found on the cfe-dev list with subject "[RFC] Easier source-to-source transformations with clang tooling".

Checking whether two regions are the same is a partially decidable problem:
either we know for sure that they are the same or we cannot decide. A typical
case for this are the symbolic regions based on conjured symbols. Two
different conjured symbols are either the same or they are different. Since
we cannot decide this and want to reduce false positives as much as possible
we exclude these regions whenever checking whether two containers are the
same at iterator mismatch check.

Summary:
This patch fixes several small problems with external layouts support in
`MicrosoftRecordLayoutBuilder`:
- aligns properly the size of a struct that ends with a bit field. It was
aligned on byte before, not on the size of the field, so the struct size was
smaller than it should be;
- adjusts the struct size when injecting a vbptr in the case when there were no
bases or fields allocated after the vbptr. Similarly, without the adjustment
the struct was smaller than it should be;
- the same fix as above for the vfptr.
All these fixes affect the non-virtual size of a struct, so they are tested
through non-virtual inheritance.

Currently we have -Rpass for filtering the remarks that are displayed as

to filter the remarks while generating them.
This adds support for filtering remarks by passes using a regex.
Ex: `clang -fsave-optimization-record -foptimization-record-passes=inline`
will only emit the remarks coming from the pass `inline`.
This adds:
* `-fsave-optimization-record` to the driver
* `-opt-record-passes` to cc1

#define foo(x) int bar() { return x; }
#define hello(fvar) fvar(0)
hello(foo)
int main() { 1 / bar(); }
Expansion of hello(foo) asserted Clang, because it expected an l_paren token in
the 3rd line after "foo", since it is a function-like token.

While it looks like FlagTypePassByValue can imply triviality and FlagTypePassByReference can imply non-triviality that is not true. Some non-trivial cases use a combination of FlagNonTrivial and FlagTypePassByValue instead of FlagTypePassByReference. See the test cases and D44406 for discussion.

example. They're the clang equivalent to the llvm-headers target and
complement the clang-libraries target.

This patch adds a bit of logic to handle these cases and documents them in
tests.
The commented-out test cases in the new test suite are ones that were
problematic before r355434.
