Summary:
Rename stop-after to stop-diff-after. When building LLVM with
-DLLVM_BUILD_LLVM_DYLIB=ON, stop-after collides with the stop-after
already present in LLVM.

Currently, in case of GEMM and the pattern matching based optimizations, we
use only the SLP Vectorizer out of two LLVM vectorizers. Since the Loop
Vectorizer can get in the way of optimal code generation, we disable the Loop
Vectorizer for the innermost loop using mark nodes and emitting the
corresponding metadata.

This was originally a `#define`. It is much easier to play around with

Patch by Rafael Espíndola.
This is PR34053.
The implementation is a bit of a hack, given the precise location where
IsPreemtible is set, it cannot be used from
SymbolTable::handleAnonymousVersion.
I could add another method to SymbolTable if you think that would be
better.

Summary:
This patch teaches ADCE to preserve both DominatorTrees and PostDominatorTrees.
This is reapplies the original patch r311057 that was reverted in r311381.
The previous version wasn't using the batch update api for updating dominators,
which in vary rare cases caused assertion failures.
This also fixes PR34258.

I was contacted by Jesper Antonsson from Ericsson who ran into problems
with r311181 in their test suites with for an out-of-tree target.
Because of the latter I don't have a reproducer, but we definitely don't
want to modify the data structure on which we are iterating inside the
loop.

I've replaced the two OS-specific runs with a generic run because
there's no functional difference in the resulting output that

Summary:
This patch is an alternative to https://reviews.llvm.org/D36614, by resolving a
non-idempotency issue by breaking non-trailing comments:
Consider formatting the following code with column limit at `V`:
```
V
const /* comment comment */ A = B;
```
The comment is not a trailing comment, breaking before it doesn't bring it under
the column limit. The formatter breaks after it, resulting in:
```
V
const /* comment comment */
A = B;
```
For a next reformat, the formatter considers the comment as a trailing comment,
so it is free to break it further, resulting in:
```
V
const /* comment
comment */
A = B;
```
This patch improves the situation by directly producing the third case.

This commit fixes a bug introduced in r307903. The attribute ambiguity checker
that was introduced in r307903 checked all property attributes, which caused
errors for source-compatible properties, like:
@property (nonatomic, readonly) NSObject *prop;
@property (nonatomic, readwrite) NSObject *prop;
because the readwrite property would get implicit 'strong' attribute. The
ambiguity checker should be concerned about explicitly specified attributes
only.

This is PR33245.
Case I am fixing is next:
Imagine we have 2 BC files, one defines and uses personality routine,
second has only declaration and also uses it.
Previously algorithm computing dead symbols (llvm::computeDeadSymbols) did
not know about personality routines and leaved them dead even if function that
has routine was live.
As a result thinLTOInternalizeAndPromoteGUID() method changed binding for
such symbol to local. Later when LLD tried to link these objects it failed
because one object had undefined global symbol for routine and second
object contained local definition instead of global.
Patch set the live root flag on the corresponding FunctionSummary
for personality routines when we build the per-module summaries
during the compile step.
