We already do this for ZERO_EXTEND/ZERO_EXTEND_VECTOR_INREG - this just extends the pattern matcher to recognize cases where we don't need the zeros in the extension.

Make DependencyFileGenerator a DependencyCollector as it was intended when
DependencyCollector was introduced. The missing PPCallbacks overrides are added to
the DependencyCollector as well.
This change will allow clang-scan-deps to access the produced dependencies without
writing them out to .d files to disk, so that it will be able collate them and
report them to the user.

This includes all the obvious bitwise operations (AND, OR, BIC, ORN,
MVN) in register-to-register forms, and the immediate forms of
AND/OR/BIC/ORN; byte-order reverse instructions; and the VMOVs that
access a single lane of a vector.
Some of those VMOVs (specifically, the ones that access a 32-bit lane)
share an encoding with existing instructions that were disassembled as
accessing half of a d-register (e.g. `vmov.32 r0, d1[0]`), but in
8.1-M they're now written as accessing a quarter of a q-register (e.g.
`vmov.32 r0, q0[2]`). The older syntax is still accepted by the
assembler.

checking for a switch that doesn't exist, so really has no purpose, at

The check against the output of `od` in the affected tests expect a
specific input offset format. They also expect a specific offset value,
not consistent with the EXAMPLE section for `od` in POSIX.1-2017
Chapter 4, while using the `-j` option. In particular, the example shows
that the input offset begins at 0 following the bytes skipped.
This patch adjusts the matching of the input offset to be more generic.
In order to avoid false matches, it restricts the number of bytes to be
formatted.

Summary:
This patch adds support for handling variables under the:
```
#pragma omp declare target to()
```
clause when the
```
#pragma omp requires unified_shared_memory
```
is used.
The address of the host variable is copied into the device pointer just like for the declare target link case.

Summary:
This patch applies a change similar to rC363069, but for SARIF files.
The `%diff_sarif` lit substitution invokes `diff` with a non-portable
`-I` option. The intended effect can be achieved by normalizing the
inputs to `diff` beforehand. Such normalization can be done with
`grep -Ev`, which is also used by other tests.
Additionally, this patch updates the SARIF output to have a newline at
the end of the file. This makes it so that the SARIF file qualifies as a
POSIX text file, which increases the consumability of the generated file
in relation to various tools.

Summary:
Specify message levels in CMake. Prefer STATUS (stdout).
As the default message mode (i.e. level) is NOTICE in CMake, more then necessary messages get printed to stderr. Some tools, noticably ccmake treat this as an error and require additional confirmation and re-running CMake's configuration step.
This commit specifies a mode (either STATUS or WARNING or FATAL_ERROR) instead of the default.
* I used `csearch -f 'llvm-project/.+(CMakeLists\.txt|cmake)' -l 'message\("'` to find all locations.
* Reviewers were chosen by the most common authors of specific files. If there are more suitable reviewers for these CMake changes, please let me know.

Previously, we attempted to write out template parameters and specializations to their own array, but due to the architecture of the ASTNodeTraverser, this meant that other nodes were not being written out. This now follows the same behavior as the regular AST dumper and puts all the (correct) information into the "inner" array. When we correct the AST node traverser itself, we can revisit splitting this information into separate arrays again.

Summary:
This patch teaches ConstantFolding to constant fold
both scalar and vector variants of llvm.smul.fix and
llvm.smul.fix.sat.
As described in the LangRef rounding is unspecified for
these instrinsics. If the result cannot be represented
exactly the default behavior in ConstantFolding is to
round down towards negative infinity. If a target has a
preferred rounding that is different some kind of target
hook would be needed (same strategy as used by the
SelectionDAG legalizer).

Vector load/store instructions support an optional alignment field
that the compiler can use to provide known alignment info to the
hardware. If the field is used (and the information is correct),
the hardware may be able (on some models) to perform faster memory
accesses than otherwise.
This patch adds support for alignment hints in the assembler and
disassembler, and fills in known alignment during codegen.

The first use of this is a code tweak to expand macro calls.
Will later be used to build syntax trees.

Using the -fdeclare-opencl-builtins option will require a way to
predefine types and macros such as `int4`, `CLK_GLOBAL_MEM_FENCE`,
etc. Move these out of opencl-c.h into opencl-c-base.h such that the
latter can be shared by -fdeclare-opencl-builtins and
-finclude-default-header.
This changes the behaviour of -finclude-default-header when
-fdeclare-opencl-builtins is specified: instead of including the full
header, it will include the header with only the base definitions.
