... and make a few ilist-internal API changes, in preparation for
changing how ilist_node is templated. The only effect for ilist users
should be changing the friend target from llvm::ilist_node_access to
llvm::ilist_detail::NodeAccess (which is only necessary when they
inherit privately from ilist_node).
- Split out SpecificNodeAccess, which has overloads of getNodePtr and
getValuePtr that are untemplated.
- Use more typedefs to prevent more changes later.
- Force inheritance to use *NodeAccess (to emphasize that ilist *users*
shouldn't be doing this).
There should be no functionality change here.

Everything under foldICmpInstWithConstant() should now be working for
splat vectors via m_APInt matchers. Ie, I've removed all of the FIXMEs
that I added while cleaning that section up. Note that not all of the
associated FIXMEs in the regression tests are gone though, because some
of the tests require earlier folds that are still scalar-only.

Summary:
I want to separate out the notions of invariance and dereferenceability
at the MI level, so that they correspond to the equivalent concepts at
the IR level. (Currently an MI load is MI-invariant iff it's
IR-invariant and IR-dereferenceable.)
First step is renaming this function.

If the literal is being folded into src0, it doesn't matter
if it's an SGPR because it's being replaced with the literal.
Also fixes initially selecting 32-bit versions of some instructions
which also confused commuting.

This would create a bitcast use which fails the verifier: swifterror values may
only be used by loads, stores, and as function arguments.

Summary:
Previously these only worked via NVPTX-specific intrinsics.
This change will allow us to convert these target-specific intrinsics
into the general LLVM versions, allowing existing LLVM passes to reason
about their behavior.
It also gets us some minor codegen improvements as-is, from situations
where we canonicalize code into one of these llvm intrinsics.

Move the target specific setup into the target specific lowering setup. As
pointed out by Anton, the initial change was moving this too high up the stack
resulting in a violation of the layering (the target generic code path setup
target specific bits). Sink this into the ARM specific setup. NFC.

Previously, gtest/gtest_main were not exported via cmake. The intention here was
to ensure that users whom are linking against the LLVM install tree would not
get the gtest/gtest_main targets. This prevents downstream projects that link
against the LLVM build tree (i.e. Swift) from getting this dependency
information in their cmake builds. Without such dependency information, linker
issues can result on linux due to LLVMSupport being put before gtest on the
linker command line.
This commit preserves behavior that we want for the install tree, while adding
support for the build tree by:
1. The special casing for gtest/gtest_main in the add_llvm_library code is
removed in favor of a flag called "BUILDTREE_ONLY". If this is set, then the
library is communicating that it is only meant to be exported into the build
tree and is not meant to be installed or exported via the install tree. This
part is just a tweak to remove the special case, the underlying code is the
same.
2. The cmake code that exports cmake targets for the build tree has special code
to import an additional targets file called
LLVMBuildTreeOnlyExports.cmake. Additionally the extra targets are added to the
LLVMConfig.cmake's LLVM_EXPORTED_TARGETS variable. In contrast, the
"installation" cmake file uses the normal LLVM_EXPORTS_TARGETS as before and
does not include the extra exports file. This is implemented by
defining/undefining variables when performing a configure of the build/install
tree LLVMConfig.cmake files.

SmallVectors are convenient, but they don't cover every use case.
In particular, they are fairly large (3 pointers + one element) and
there is no way to take ownership of the buffer to put it somewhere
else. This patch then adds a lower lever interface that works with
any buffer.

We have various command line options that print the type of a
stream, the size of a stream, etc but nowhere that it can all be
viewed together.
Since a previous patch introduced the ability to dump the bytes
of a stream, this seems like a good place to present a full view
of the stream's properties including its size, what kind of data
it represents, and the blocks it occupies. So I added the
ability to print that information to the -stream-data command
line option.

These asserts are making tests fragile. The renderer does not enter an
invalid state when they fail, however, it may spit out a garbled
coverage report because the source text no longer matches the provided
coverage mapping.
Another follow-up to r281072.

This time, add quotes around llvm-{cov,config} so that lit won't expand

I ran into a situation where I wanted to print out the contents of
page 6 of a PDB as a binary blob, and there was no straightforward
way to do that.
In addition to adding that, this patch also adds the ability to dump
a stream by index as a binary blob, and it will stitch together all
the blocks and dump the whole thing as one seemingly contiguous
sequence of bytes.

This simplifies a lot of code, and will actually be necessary for
an upcoming patch to serialize TPI record hash values.
The idea before was that visitors should be examining records, not
modifying them. But this is no longer true with a visitor that
constructs a CVRecord from Yaml. To handle this until now, we
were doing some fixups on CVRecord objects at a higher level, but
the code is really awkward, and it makes sense to just have the
visitor write the bytes into the CVRecord. In doing so I uncovered
a few bugs related to `Data` and `RawData` and fixed those.
