Craig Topper 4431bfe88c [InstCombine] Support vector splats in transformZExtICmp
This patch adds splat support to transformZExtICmp. The test cases are vector versions of tests that failed when commenting out parts of the existing scalar code.

One test didn't vectorize optimize properly due to another bug so a TODO has been added.

Hans Wennborg e7becd7e85 [DAG] Bound loop dependence check in merge optimization.
The loop dependence check looks for dependencies between store merge
candidates not captured by the chain sub-DAG doing a check of
predecessors which may be very large. Conservatively bound number of
nodes checked for compilation time. (Resolves PR34326).

Landing on behalf of Nirav Dave to unblock the 5.0.0 release.

Michael Kruse 99cc9ded41 Do not consider mem intrinsics as error.
The intrinsics memset, memcopy and memmove do have their memory accesses
modeled by ScopBuilder. Do not consider them error-case behavior.

Test case will come with a future patch that requires memory intrinsics
outside of error blocks.

Michael Kruse 25d3f85a43 Skip ignored intrinsics.
Commit r252725 introduced a "return false" if an ignored intrinsics was
found. The consequence of this was that the mere existence of an ignored
intrinsic (such as llvm.dbg.value) before a call that would have
qualified the block to be an error block, to not be an error block.

The obvious goal was to just skip ignored intrinsics, not changing the
meaning of what an error block is.

Teresa Johnson 2df7fc7991 [ThinLTO] Clean up stale alias import handling
Summary:
Remove some code that was no longer needed. The first FIXME is

rather than doing force importing based on linkage type. And
now with r309278, we no longer import any aliases.

Reid Kleckner dd6fc83cb4 [ms] Fix vbtable index for covariant overrides of vbase methods
Overriding a method from a virtual base with a covariant return type
consumes a slot from the vftable in the virtual base. This can make it
impossible to implement certain diamond inheritance hierarchies, but we
have to follow along for compatibility in the simple cases.

This patch only affects our vtable dumper and member pointer function
mangling, since all other callers of getMethodVFTableLocation seem to
recompute VBTableIndex instead of using the one in the method location.

Dehao Chen efd007f6f4 Add null check for promoted direct call
Summary: We originally assume that in pgo-icp, the promoted direct call will never be null after strip point casts. However, stripPointerCasts is so smart that it could possibly return the value of the function call if it knows that the return value is always an argument. In this case, the returned value cannot cast to Instruction. In this patch, null check is added to ensure null pointer will not be accessed.

George Rimar db21e5324a [ELF] - Linkerscript: add test for checking interaction with archive files.
Imagine we have archive file with symbols foo and bar.
And script that do foo = 1.
In that case correct behavior is not to fetch symbols from archive but
create absolute symbol. 
If we have script zed = foo then symbol foo will be fetched from archive.
Currently we have Opt.ReferencedSymbols list of symbols referenced
by script and create them undefined early. That allows archives fetching logic 
to work. That is what LLD already do and it seems everything is fine here.

But during writing D37059 I had to add left side of assignments to
Opt.ReferencedSymbols list because wanted to stop optimizing out
these symbols when LTO is involved (LTO also uses this list). 
And testcase from this patch would have fail if we would have it before.

Summary:
This change hides all the initialization of thread_local variables used

initialization of thread-local data to be done lazily, instead of
eagerly when they're done as globals. It also gives us an isolation
mechanism if/when we want to change the TLS implementation from using
the C++ thread_local keyword, for something more ad-hoc (potentialy
using pthread directly) on some platforms or set-ups where we cannot use
the C++ thread_local variables.

Raphael Isemann d8132c303e [modules] Add test for using declaration in classes.
Summary:
This adds a test that checks if the using declaration in classes still works as intended with modules.

The motivation for this is that we tried to add a shortcut to `removeDecl` that would skip the removal of declarations from the lookup table if they are hidden. This optimization passed the clang test suite but actually broke the using declaration in combination with -fmodules-local-submodule-visibility. In this mode we hide all decls from other modules such as by chance the parent method, in which case don't remove the parent method from the lookup table and get ambiguous lookup errors. After this patch we now correctly see if this behavior is broken by a patch like this in the test suite.

Martin Probst c10d97f924 clang-format: [JS] simplify template string wrapping.
Summary:
Previously, clang-format would try to wrap template string substitutions
by indenting relative to the openening `${`. This helped with
indenting structured strings, such as strings containing HTML, as the
substitutions would be aligned according to the structure of the string.

However it turns out that the overwhelming majority of template string +
substitution usages are for substitutions into non-structured strings,
e.g. URLs or just plain messages. For these situations, clang-format
would often produce very ugly indents, in particular for strings
containing no line breaks:

    return `<a href='http://google3/${file}?l=${row}'>${file}</a>(${
                                                                    row
                                                                  },${
                                                                      col
                                                                    }): `;

This change makes clang-format indent template string substitutions as
if they were string concatenation operations. It wraps +4 on overlong
lines and keeps all operands on the same line:

    return `<a href='http://google3/${file}?l=${row}'>${file}</a>(${
        row},${col}): `;

While this breaks some lexical continuity between the `${` and `row}`
here, the overall effects are still a huge improvement, and users can
still manually break the string using `+` if desired.

When LSR processes code like

It may decide to replace integer `accumulator` with a double Shadow IV to get rid

Starting from this moment, the behavior of integer and double accumulators
will differ.

This patch strenghtens up the conditions of Shadow IV mechanism applicability.

Michal Gorny a81de445c1 [cmake] Support running extra clang tool tests without static analyzer
Support running the extra clang tool tests when the static analyzer
is disabled. Disable the relevant clang-tidy tests and one include-fixer
test that require it to work.

Previously, the tests were disabled entirely with
CLANG_ENABLE_STATIC_ANALYZER being false. Now, the tests are being
enabled and the relevant tests are excluded and marked unsupported
appropriately.

In order to disable clang-tidy tests, the whole test directory is added
to the exclude lists, to avoid having to explicitly add 'REQUIRES' line
to every single test. If the other solution is preferable, I can update
the patch.

The yamldb_plugin include-fixer test is also updated to be disabled
without static analyzer. It fails in that case because clang is not
outputting a replacement suggestion -- but I don't know the exact
reason why it does not do that.
