This patch provides optimization of bit manipulation operations by
enabling the +experimental-b target feature.
It adds matching of single block patterns of instructions to specific
bit-manip instructions from the ternary subset (zbt subextension) of the
experimental B extension of RISC-V.
It adds also the correspondent codegen tests.
This patch is based on Claire Wolf's proposal for the bit manipulation
extension of RISCV:

This fixes an instance where MemorySSA-using Dead Store Elimination is failing
to do a transformation that the non-MemorySSA-using version does.
Differential Revision: https://reviews.llvm.org/D83783
The actual rotation happens in processLoop, so the second removed
call to verifyMemorySSA was unnecessary.
In fact, processLoop/rotateLoop already verify MemorySSA before
and after transforming each loop. Hence, both calls can be removed.
Pointed out by @lebedev.ri post-commit D51718.
Summary:
Without these, the generic branch relaxation pass will underestimate the
range required for branches spanning these and we can end up with
"fixup value out of range" errors rather than relaxing the branches.
Some of the instructions in the expansion may end up being compressed
but exactly determining that is awkward, and these conservative values
should be safe, if slightly suboptimal in rare cases.

In D83482 we agreed to name e_* fields that are used for overriding

Currently we have a set of e_sh* fields that are named inconsistently
with this rule. This patch renames all of them.

In 2b3c505, the pointer arguments for the matrix load and store
intrinsics was changed to always be the element type of the vector
argument.
This patch updates the MatrixBuilder to not add the pointer type to the
overloaded types and adjusts the clang/mlir tests.
This should fix a few build failures on GreenDragon, including
http://green.lab.llvm.org/green/job/test-suite-verify-machineinstrs-x86_64-O0-g/7891/
This improves condition in the ELFFile::program_headers().
Previously if was possible to read the headers from the wrong place when
the value of e_phoff was so large that computation overflowed.

Some of the system registers readable on AArch64 and ARM platforms
return different values with each read (for example a timer counter),
these shouldn't be hoisted outside loops or otherwise interfered with,
but the normal @llvm.read_register intrinsic is only considered to read
memory.
This introduces a separate @llvm.read_volatile_register intrinsic and
maps all system-registers on ARM platforms to use it for the
__builtin_arm_rsr calls. Registers declared with asm("r9") or similar
are unaffected.
The existing code already considered this case. Unfortunately a typo in
the condition prevents it from triggering. Also the existing code, had
it run, forgot to do the folding.
This fixes PR42876.

Summary:
This change avoids exposing tensorflow types when including TFUtils.h.
They are just an implementation detail, and don't need to be used
directly when implementing an analysis requiring ML model evaluation.
The TFUtils APIs, while generically typed, are still not exposed unless
the tensorflow C library is present, as they currently have no use
otherwise.

The dependencies in llvm/unittests/Transforms/IPO/CMakeLists.txt
introduced in revision 0750757e were incomplete, leading to link errors
for a DBUILD_SHARED_LIBS=True build.
During code generation we might change/add basic blocks so keeping a
list of them is fairly easy to break. Nested parallel regions were
enough. The new scheme does recompute the list of blocks to be outlined
once it is needed.

Since D82572, we keep "reference" edges for callback call sites. While
not strictly necessary they can improve the traversal order. However, we
did not update them properly in case a pass removed the callback call
site which caused a verification error (PR46687). With this patch we
update these reference edges properly during the invocation of
`CallGraphSCCPass::RefreshCallGraph` in non-checking mode.

Rather than handling zlib handling manually, use find_package from CMake
to find zlib properly. Use this to normalize the LLVM_ENABLE_ZLIB,
HAVE_ZLIB, HAVE_ZLIB_H. Furthermore, require zlib if LLVM_ENABLE_ZLIB is
set to YES, which requires the distributor to explicitly select whether
zlib is enabled or not. This simplifies the CMake handling and usage in
the rest of the tooling.
This is a reland of abb0075 with all followup changes and fixes that
should address issues that were reported in PR44780.

This caused crashes during deallocation in C++14 builds when using a

Also make the LazyCallThroughManager destructor protected to catch this

Summary:
This allows users of the llvm library discover whether llvm was built
with the tensorflow c API dependency, which helps if using the TFUtils
wrapper, for example.
We don't do the same for the LLVM_HAVE_TF_AOT flag, because that does

Instead of detecting it automatically but also allowing for the setting

based on whether -fno-rtti (or equivalent) is used. It's less confusing
to have a single way of tweaking that knob.
