This reverts commit r330016.
The incomplete detection has too many false positives, picking up typos
for hard failures and refusing to format anything in that case.

Should be a harmless trimming of trailing whitespace from a
documentation file.
(There are other instances of trailing whitespace in this file alone.
I've only fixed one of them, on the basis that that way the rest are
still available for other people's commit-access tests :-)

If an atomic variable is misaligned (and that suspicion is why Clang emits
libcalls at all) the runtime support library will have to use a lock to safely
access it, with potentially very bad performance consequences. There's a very
good chance this is unintentional so it makes sense to issue a warning.
Also give it a named group so people can promote it to an error, or disable it
if they really don't care.

The condition this was asserting doesn't actually hold. I've added
comments to explain why, removed the assert, and added a fun test case
reduced out of 403.gcc.

r327219 added wrappers to std::sort which randomly shuffle the container before
sorting. This will help in uncovering non-determinism caused due to undefined
sorting order of objects having the same key.
To make use of that infrastructure we need to invoke llvm::sort instead of
std::sort.

The SandyBridge BMI tests are actually run on IvyBridge as that's the first lowest CPU that actually support the ISAs (but still use the SandyBridge model).

This is the last step in getting constant pattern matchers to allow
undef elements in constant vectors.
I'm adding a dedicated m_ZeroInt() function and building m_Zero() from
that. In most cases, calling code can be updated to use m_ZeroInt()
directly when there's no need to match pointers, but I'm leaving that
efficiency optimization as a follow-up step because it's not always
clear when that's ok.
There are just enough icmp folds in InstSimplify that can be used for
integer or pointer types, that we probably still want a generic m_Zero()
for those cases. Otherwise, we could eliminate it (and possibly add a
m_NullPtr() as an alias for isa<ConstantPointerNull>()).
We're conservatively returning a full zero vector (zeroinitializer) in
InstSimplify/InstCombine on some of these folds (see diffs in InstSimplify),
but I'm not sure if that's actually necessary in all cases. We may be
able to propagate an undef lane instead. One test where this happens is
marked with 'TODO'.

Summary:
`llvm-bcanalyzer` prints out the stream type of the file it is
analyzing. If the file begins with the LLVM IR magic number, it reports
a stream type of "LLVM IR". However, any other bitstream format is
reported as "unknown".
Add some checks for two other common bitstream formats: Clang AST
files, which begin with 'CPCH', and Clang serialized diagnostics, which
begin with 'DIAG'.
Test Plan: `check-llvm`

This commit has been breaking most bots for a day now. There is a fix
proposed in https://reviews.llvm.org/D45912 but when I applied that
I just got different errors. Reverting to get our bots back to green.

Several tools prefix the error/warning/note output with the name of the
tool. One such tool is LLD for example. This commit adds as an optional
'Prefix' argument to the convenience helpers.
