Add module dependencies (header files, module map files) to the list of
files to check when deciding whether to rebuild a preamble. That fixes
using preambles with module imports so long as they are in
non-overridden files.
My intent is to use to unify the existing dependency collectors to the
new “DependencyCollectory” interface from this commit, starting with the
DependencyFileGenerator.

Upon encountering a binary operator inside parentheses, assume that the
parentheses contain an expression.
Before:
MACRO('0' <= c&& c <= '9');
After:
MACRO('0' <= c && c <= '9');

This worked initially but was broken by r210887.
Before:
function outer1(a, b) {
function inner1(a, b) { return a; } inner1(a, b);
} function outer2(a, b) { function inner2(a, b) { return a; } inner2(a, b); }
After:
function outer1(a, b) {
function inner1(a, b) { return a; }
inner1(a, b);
}
function outer2(a, b) {
function inner2(a, b) { return a; }
inner2(a, b);
}
Thanks to Adam Strzelecki for working on this.

This removes a const_cast added in r211884 that occurred due to an
inconsistency in how MemoryBuffers are handled between some parts of
clang and LLVM.
MemoryBuffers are immutable and the general convention in the LLVM
project is to omit const from immutable types as it's simply
redundant/verbose (see llvm::Type, for example). While this change
doesn't remove "const" from /every/ MemoryBuffer, it at least makes this
chain of ownership/usage consistent.

For now, this is only used by its unit tests. It is similar to the API
in llvm::sys::fs::recursive_directory_iterator, but without some of the
more complex features like requesting that the iterator not recurse into
the next directory, for example.

1) missing iterator bits needed by libstdc++4.7
Using find_if was convenient, but since operator++ wasn't a good
interface anyway, I just replaced with a range-based for loop and
removed operator++ from the directory_iterator class.
2) stop relying on order of iterating real files
llvm-svn: 211633
The API is based on sys::fs::directory_iterator, but it allows iterating
over overlays and the yaml-based VFS. For now, it isn't used by
anything (except its tests).

Something went wrong with r211426, it is an older version of this code
and should not have been committed. It was reverted with r211434.
Original commit message:
We didn't properly implement support for the sized integer suffixes.
Suffixes like i16 were essentially ignored instead of mapping them to
the appropriately sized integer type.
This fixes PR20008.

This reverts commit r211426.
This broke the arm bots. The crash can be reproduced on X86 by running.

Summary:
Do not store duplicate parents when memoization data is available.
This does not solve the duplication problem, but ameliorates it.

will never be true in a well-defined context. The checking for null pointers
has been moved into the caller logic so it does not rely on undefined behavior.

Before (JavaScript example, but can extend to other languages):
return {
a: 'E',
b: function() {
return function() {
f(); // This is wrong.
};
}
};
After:
return {
a: 'E',
b: function() {
return function() {
f(); // This is better.
};

These are commonly used to structure things like enums or long braced
lists. There doesn't seem to be a good reason to have the behavior in
such structures be different from the behavior between statements.

This corrects long-standing misuses of LLVM's internal config.h.
In most cases the public llvm-config.h header was intended and we can now
remove the old hacks thanks to LLVM r210144.
The config.h header is private, won't be installed and should no longer be
included by clang or other modules.

There is a pattern where evaluation order is used as control flow.
This patch special-cases a commonly occuring version of this pattern.
Before:
Aaaaa *aaa = nullptr;
// ...
aaa &&aaa->f();
After:
Aaaaa *aaa = nullptr;
// ...
aaa && aaa->f();
