The later API is nicer than the former, and is correct regarding wrap-around offsets (if anyone cares).
There are a few more places left with duplicated code, which I'll remove soon.

This is in preparation for removing the use of the 'Attribute' class as a
collection of attributes. That will shift to the AttributeSet class instead.

LCSSA PHIs may have undef values. The vectorizer updates values that are used by outside users such as PHIs.
The bug happened because undefs are not loop values. This patch handles these PHIs.

This is done to avoid odd test failures, like the one fixed in r171243.

* One that accepts a single Attribute::AttrKind.

* One that accepts an Attribute::AttrKind plus a list of values. This is for
  attributes defined like this:

    #1 = attributes { align = 4 }

* One that accepts a string, for target-specific attributes like this:

    #2 = attributes { "cpu=cortex-a8" }

This test did not test anything at all (except for opt crashing, but that was
not the reason why it was added).

stored here is of a certain kind. This is in preparation for when an Attribute
object represents a single attribute, instead of a bitmask of attributes.

Note: This will be expanded in the future to add more than just one pointer
value.

assert(Condition

->

assert(Condition &&
       "Text);

This aligns Polly with the style used in LLVM.

We fix the following formatting problems found by clang-format:

  - 80 cols violations
  - Obvious problems with missing or too many spaces
  - multiple new lines in a row

clang-format suggests many more changes, most of them falling in the following
two categories:

  1) clang-format does not at all format a piece of code nicely

  2) The style that clang-format suggests does not match the style used in
     Polly/LLVM

I consider differences caused by reason 1) bugs, which should be fixed by
improving clang-format. Differences due to 2) need to be investigated closer
to understand the cause of the difference and the solution that should be taken.

This fixes pr14736. It is fairly ugly, but I don't think we can do much better
as we have to wait at least until the end of the typedef to know if the
function will have external linkage or not.

Remove intrinsic specific instructions for (V)SQRTPS/PD. Instead lower to target-independent ISD nodes and use the existing patterns for those.

Remove test for eof from istreambuf_iterator constructors.  It is no longer necessary and potentially violates the constructor's noexcept spec.

Remove intrinsic specific instructions for SSE/SSE2/AVX floating point max/min instructions. Lower them to target specific nodes and use those patterns instead. This also allows them to be commuted if UnsafeFPMath is enabled.

to read and tell that it is a SWO -- we now descend through the
components and return a result at the first inequal component.

Also comment it a bit better and make it a total ordering by sorting on
the text of the suffix if necessary.

None of this should really be a visible change.

DS parameter  has a default (null) value anyway, so there's no need for an

inlined.  These do not need to be always-inlined for ABI stability because they are not exported beyond this source due to the unnamed namespace.
Also simplified use of the Wmissing-field-initializers pragma as was done for clang.
