This unblocks the new PM part of River's patch in
https://reviews.llvm.org/D22706

Conveniently, this same change was needed for D21921 and so these
changes are just spun out from there.

Additionally, for pre-C++1z, instead of forbidding a lambda's closure type from being a literal type through circumlocutorily setting HasNonLiteralTypeFieldsOrBases falsely to true -- handle lambda's more directly in CXXRecordDecl::isLiteral().

One additional small step towards implementing constexpr-lambdas.

Thanks to Richard Smith for his review!

This is the first patch in the coroutine series.
It contains the documentation for the coroutine intrinsics and their usage.

While we handed loads past the end of an array, we didn't handle loads
_before_ the array.

This fixes PR28062.

N.B. While the bug in the code is obvious, I am struggling to craft a
test case which is reasonable in size.

allocate no more than two of these at a time, on the stack).

There is a bug in Clang 3.6 and earlier that causes compile failures.
I suspect it's due to the usage of member function parameter names in the
attributes.

Summary:
This patch uses the __attribute__((enable_if)) hack suggested by @rsmith to diagnose invalid arguments when possible.

In order to diagnose an invalid argument `m` to `f(m)` we provide an additional overload of `f` that is only enabled when `m` is invalid. When that function is enabled it uses __attribute__((unavailable)) to produce a diagnostic message.

This change lets us prove things like

  "{X,+,10} s< 5000" implies "{X+7,+,10} does not sign overflow"

It does this by replacing replacing getConstantDifference by
computeConstantDifference (which is smarter) in
isImpliedCondOperandsViaRanges.

It's been pointed out that arbitrarily spraying raw profiles into a
build directory is insane. Doing this wastes a tremendous amount of
space and is also very lossy, since the test harness tends to wipe away
temporary sub-directories (which usually contain relevant profile data).

The new default is a `profiles` directory inside of the build dir.

llvm-svn: 276504

This is in preparation of
s/getConstantDifference/computeConstantDifference/ in a later change.

Only around 50% of the intrinsics in this file are documented now. The patches for the rest of the intrisics in this file will be send out later.

The doxygen comments are automatically generated based on Sony's intrinsics docu
ment.

I got an OK from Eric Christopher to commit doxygen comments without prior code
review upstream. This patch was internally reviewed by Paul Robinson.

This reverts commit r276298.

Data stored in .rodata can have a negative offset from .text, but we
don't support negative values in relocations yet.

decomposition declarations.

There are a couple of things in the wording that seem strange here:
decomposition declarations are permitted at namespace scope (which we partially
support here) and they are permitted as the declaration in a template (which we
reject).
