After the format change from D69471, there can be more than one section
in an object that contains coverage function records. Look up each of
these sections and concatenate all the records together.
This re-enables the instrprof-merging.cpp test, which previously was
failing on OSes which use comdats.
Thanks to Jeremy Morse, who very kindly provided object files from the
bot I broke to help me debug.
We always want to build the table of contents. Additionally, we also
set the flag to make the output deterministic which is already the
default for llvm-ar.

Summary:
This function is (supposed) to be a list of asserts that just do a generic sanity check
on declarations we return. Right now this function is hidden behind the
LLDB_CONFIGURATION_DEBUG macro which means it will *only* be run in
debug builds (but not Release+assert builds and so on).
As we have not a single CI running in Debug build, failures in VerifyDecl are hidden
from us until someone by accident executes the tests in Debug mode on their own machine.
This patch removes the `ifdef`'s for LLDB_CONFIGURATION_DEBUG and puts
the `getAccess()` call in `VerifyDecl` behind a `#ifndef NDEBUG` to make sure
that this function is just an empty function with internal linkage when NDEBUG
is defined (so compilers should just optimize away the calls to it).

CFI instructions can only safely be outlined when the outlined call is a tail
call, or when the outlined frame is fixed up.
For the sake of correctness, disable outlining from CFI instructions.
Add machine-outliner-cfi.mir to test this.
Previously we would also accept DISubprograms that matched in name
only, but this doesn't appear to be necessary any more.
I did a Full and Thin LTO build of Clang and it completed without a warning.
Differential Revision: https://reviews.llvm.org/D75213
Summary:
Fixes an issue that cropped up after the changes in D73242 to delay
the lowering of type tests. LTT couldn't handle any type tests with
non-string type id (which happens for local vtables, which we try to
promote during the compile step but cannot always when there are no
exported symbols).
We can simply treat the same as having an Unknown resolution, which
delays their lowering, still allowing such type tests to be used in
subsequent optimization (e.g. planned usage during ICP). The final
lowering which simply removes these handles them fine.
Beefed up an existing ThinLTO test for such unpromoted type ids so that
the internal vtable isn't removed before lower type tests, which hides
the problem.

Make computeConversionSet bubble up errors from nested regions. Note
that this doesn't change top-level behavior - since the nested region

Summary:
Current peeling implementation bails out in case of loop nests.
The patch introduces a field in TargetTransformInfo structure that
certain targets can use to relax the constraints if it's
profitable (disabled by default).
Also additional option is added to enable peeling manually for
experimenting and testing purposes.

Summary:
This revision adds padding for 1-D Vector in the common case of x86
execution with a stadard data layout. This supports properly interfacing
codegen with arrays of e.g. `vector<9xf32>`.
Such vectors are already assumed padded to the next power of 2 by LLVM
codegen with the default x86 data layout:
```
define void @test_vector_add_1d_2_3(<3 x float>* nocapture readnone %0,
<3 x float>* nocapture readonly %1, i64 %2, i64 %3, i64 %4, <3 x float>*
nocapture readnone %5, <3 x float>* nocapture readonly %6, i64 %7, i64
%8, i64 %9, <3 x float>* nocapture readnone %10, <3 x float>* nocapture
%11, i64 %12, i64 %13, i64 %14) local_unnamed_addr {
%16 = getelementptr <3 x float>, <3 x float>* %6, i64 1
%17 = load <3 x float>, <3 x float>* %16, align 16
%18 = getelementptr <3 x float>, <3 x float>* %1, i64 1
%19 = load <3 x float>, <3 x float>* %18, align 16
%20 = fadd <3 x float> %17, %19
%21 = getelementptr <3 x float>, <3 x float>* %11, i64 1
```
The pointer addressing a `vector<3xf32>` is assumed aligned `@16`.
Similarly, the pointer addressing a `vector<65xf32>` is assumed aligned
`@512`.
This revision allows using objects such as `vector<3xf32>` properly with
the standard x86 data layout used in the JitRunner. Integration testing
is done out of tree, at the moment such testing fails without this
change.

These declarations use a mix of unsigned and signed argument and

Summary: This review is a mostly trivial change to use an explicit ABI flag for the unstable external template list. This follows the practice for an ABI flag per feature, and provides a spot for the rational / motivation for the flag.

Summary:
Enabling _GLIBCXX_DEBUG (implied by LLVM_ENABLE_EXPENSIVE_CHECKS) causes
std::min_element (and presumably others) to no longer be constexpr, which
in turn causes the build to fail.
This seems like a bug in the GCC STL. This change works around it.

- Remove unnecessary includes from the headers
- Fix cppcheck definition/declaration arg mismatch warnings
- Tidyup old comments (MVT usage was removed a long time ago)
- Use SmallVector::append for repeated mask entries
getReductionVars, getInductionVars and getFirstOrderRecurrences were all
being returned from LoopVectorizationLegality as pointers to lists. This
just changes them to be references, cleaning up the interface slightly.

I'm making the CHECK lines vague enough that they pass at -O0.
If that is too vague (we really want to check the data flow
to verify that the variables are not mismatched, etc), then
we can adjust those lines again to more closely match the output
at -O0 rather than -O1.
This change is based on the post-commit comments for:

Summary:
This patch reverts 2c5ee78de1,
now kythe (https://github.com/kythe/kythe/issues/4381) supports returning ctors refs as part of class references, so
there is no need to query the ctor refs in the index (this would also
make the results worse, lots of duplications)

There are no failures from the first set of RUN lines here,
so the CHECKs were already vague enough to not be affected
by optimizations. The final RUN line does induce some kind
of failure, so I'll try to fix that separately in a
follow-up.
Summary:
Disable merging of Type? into a single token.
Merge ?? ?. and ?[ into a single token.
