I took a guess at the changes to the gold plugin, because that doesn't
seem to build by default for me. Not sure what dependencies I might be
missing for that.

Anton Yartsev 94e46f3eb8 Enhance the 'Vectors and Extended Vectors' section.
Added cast operations to the table of vector operations. Supported status 'no' means that there are no tests in the Clang test suite for the given cast.

Sanjay Patel 9433a28845 Preserve IR flags (nsw, nuw, exact, fast-math) in SLP vectorizer (PR20802).
The SLP vectorizer should propagate IR-level optimization hints/flags (nsw, nuw, exact, fast-math)
when converting scalar instructions into vectors. But this isn't a simple copy - we need to take
the intersection (the logical 'and') of the sets of flags on the scalars.

The solution is further complicated because we can have non-uniform (non-SIMD) vector ops after:
http://reviews.llvm.org/D4015
http://llvm.org/viewvc/llvm-project?view=revision&revision=211339

The vast majority of changed files are existing tests that were not propagating IR flags, but I've
also added a new test file for focused testing of IR flag possibilities.

Rafael Espindola 688121571a Pass a && to getLazyBitcodeModule.
This forces callers to use std::move when calling it. It is somewhat odd to have
code with std::move that doesn't always move, but it is also odd to have code
without std::move that sometimes moves.

David Blaikie 99b96f42d6 Ensure ErrorOr cannot implicitly invoke explicit ctors of the underlying type.
An unpleasant surprise while migrating unique_ptrs (see changes in
lib/Object): ErrorOr<int*> was implicitly convertible to
ErrorOr<std::unique_ptr<int>>.

Keep the explicit conversions otherwise it's a pain to convert
ErrorOr<int*> to ErrorOr<std::unique_ptr<int>>.

I'm not sure if there should be more SFINAE on those explicit ctors (I
could check if !is_convertible && is_constructible, but since the ctor
has to be called explicitly I don't think there's any need to disable
them when !is_constructible - they'll just fail anyway. It's the
converting ctors that can create interesting ambiguities without proper
SFINAE). I had to SFINAE the explicit ones because otherwise they'd be
ambiguous with the implicit ones in an explicit context, so far as I
could tell.

The converting assignment operators seemed unnecessary (and similarly
buggy/dangerous) - just rely on the converting ctors to convert to the
right type for assignment instead.

Tom Stellard c4e0c1075b CGBuiltin: Use @llvm.fabs rather than fabs libcall when emitting builtins
Using the intrinsic allows the SelectionDAGBuilder to turn this call
into the FABS Node and also the intrinsic is something the vectorizer knows
how to vectorize.

This patch also sets the readnone attribute on this call, which should
enable additional optmizations.

Ed Schouten ca98874943 Allow a scoped lockable object to acquire/release multiple locks.
Scoped lockable objects (mutex guards) are implemented as if it is a
lock itself that is acquired upon construction and unlocked upon
destruction. As it if course needs to be used to actually lock down
something else (a mutex), it keeps track of this knowledge through its
underlying mutex field in its FactEntry.

The problem with this approach is that this only allows us to lock down
a single mutex, so extend the code to use a vector of underlying
mutexes. This, however, makes the code a bit more complex than
necessary, so subclass FactEntry into LockableFactEntry and
ScopedLockableFactEntry and move all the logic that differs between
regular locks and scoped lockables into member functions.

Justin Bogner 33a2a2ed1a test: Allow using clang -verify for failures rather than exit 1
Currently, failure tests work by checking that compilation exits 1.
This can lead to tests that fail for the wrong reason, so it'd be
preferable to convert them to check for specific errors.

This adds use_clang_verify parameter that runs failure tests using
clang's -verify flag. I'll convert some tests in subsequent commits,
and once all of the tests are converted we should key this on whether
cxx_under_test is clang.

I've also converted one of the unique.ptr tests, since it's the one
that motivated the idea of using clang -verify when possible in the
review of r216317.
