Hans Wennborg 4ae76c2692 clang-cl: make /Wall turn on both -Wall and -Wextra (PR25563)
The documentation suggests /Wall should really turn on -Wextra and any
other warnings that are not enabled by default. That would correspond
to Clang's -Weverything, but is probably not what users want.

David Majnemer bbfc7219ef [IR] Remove terminatepad
It turns out that terminatepad gives little benefit over a cleanuppad
which calls the termination function.  This is not sufficient to
implement fully generic filters but MSVC doesn't support them which
makes terminatepad a little over-designed.

Depends on D15478.

David Majnemer feeefb214d [MS ABI] Don't rely on terminatepad
We'd like to remove support for terminatepad from LLVM.  To do this, we
need to move Clang off of it first.  The intent behind terminatepad was
to carefully model exception specifications for the MSVC personality.

However, we don't support exception specifications for the MSVC
personality and neither does MSVC.  Instead, MSVC supports
all-or-nothing exception specifications.  We can model this limited
usage using cleanuppads which call std::terminate.

Paul Robinson accc3e0376 FastISel needs to remove dead code when it bails out.
When FastISel fails to translate an instruction it hands off code
generation to SelectionDAG. Before it does so, it may have generated
local value instructions to feed phi nodes in successor blocks. These
instructions will then be generated again by SelectionDAG, causing
duplication and less efficient code, including extra spill
instructions.

Sanjay Patel f727e387be [InstCombine] fold trunc ([lshr] (bitcast vector) ) --> extractelement (PR25543)
This is a fix for PR25543:
https://llvm.org/bugs/show_bug.cgi?id=25543

The idea is to take the existing fold of:
bitcast ( trunc ( lshr ( bitcast X))) --> extractelement (bitcast X)
( http://reviews.llvm.org/rL112232 )

And break it into less specific transforms so we'll catch more cases such as
the example in the bug report:
bitcast ( trunc ( lshr ( bitcast X))) -->
bitcast ( extractelement (bitcast X)) -->
extractelement (bitcast X)

Tobias Grosser f4f6870ff2 Revert "Always treat scalar writes as MUST_WRITEs"
This reverts commit r255471.

Johannes raised in the post-commit review of r255471 the concern that PHI
writes in non-affine regions with two exiting blocks are not really MUST_WRITE,
but we just know that at least one out of the set of all possible PHI writes
will be executed. Modeling all PHI nodes as MUST_WRITEs is probably save, but
adding the needed documentation for such a special case is probably not worth
the effort. Michael will be proposing a new patch that ensures only a single
PHI_WRITE is created for non-affine regions, which - besides other benefits -
should also allow us to use a single well-defined MUST_WRITE for such PHI
writes.

(This is not a full revert, but the condition and documentation have been
slightly extended)

Kuba Brecka 2cdb522a5a [tsan] Update dispatch_group support to avoid using a disposed group object
We're using the dispatch group itself to synchronize (to call Release() and Acquire() on it), but in dispatch group notifications, the group can already be disposed/deallocated. This causes a later assertion failure at `DCHECK_EQ(*meta, 0);` in `MetaMap::AllocBlock` when the same memory is reused (note that the failure only happens in debug builds).

Fixing this by retaining the group and releasing it in the notification. Adding a stress test case that reproduces this.

Pavel Labath ffbf9e86b2 Make test categories composable
Summary:
Previously the add_test_categories would simply overwrite the current set of categories for a
method. This change makes the decorator truly "add" categories, by extending the current set of
categories instead of replacing it.

To do this, I have:
- replaced the getCategories() property on a method (which was itself a method), with a simple
  list property "categories". This makes add_test_categories easier to implement, and test
  categories isn't something which should change between calls anyway.
- rewritten the getCategoriesForTest function to merge method categories with the categories of
  the test case. Previously, it would just use the method categories if they were present. I have
  also greatly simplified this method. Originally, it would use a lot of introspection to enable
  it being called on various types of objects. Based on my tests, it was only ever being called
  on a test case. The new function uses much less introspection then the preivous one, so we
  should easily catch any stray uses, if there are any, as they will generate exceptions now.

James Molloy 2b1e101e99 Don't create unnecessary PHIs
In conditional store merging, we were creating PHIs when we didn't
need to. If the value to be predicated isn't defined in the block
we're predicating, then it doesn't need a PHI at all (because we only
deal with triangles and diamonds, any value not in the predicated BB
must dominate the predicated BB).

This fixes a large code size increase in some benchmarks in a popular embedded benchmark suite.

Revision 251405 added AlwaysBreak to support Google's JavaScript style. This
changeset complete existing AlignsAfterOpenBracket tests to exercise
AlwaysBreak for C++.

I thought this would be worthwhile.  With this option we can support request
from http://lists.llvm.org/pipermail/cfe-dev/2015-May/042942.html, that had
been requested a few times. This also partially solve related Bug 23422 and is
probably sufficient for most people.

  AlignAfterOpenBracket = FormatStyle::BAS_AlwaysBreak;
  BinPackArguments = false;
  BinPackParameters = false;

With these setting we obtain this formatting:

  void fooWithAVeryLongParamList(
      int firstParameter,
      int secondParameter
      int lastParameter)
  {
      object.alsoThisDoenstFitSoIBreakImmidiatly(
