[SVE][CodeGen] Fix bug in DAGCombiner::reduceBuildVecToShuffle

When trying to reduce a BUILD_VECTOR to a SHUFFLE_VECTOR it's
important that we carefully check the vector types that led to
that BUILD_VECTOR. In the test I have attached to this commit
there is a case where the results of two SVE faddv instructions
are being stored to consecutive memory locations. With my fix,
as part of merging those stores we discover that each BUILD_VECTOR
element came from an extract of a SVE vector element and
therefore bail out.

[llvm-objcopy][MachO] Fix segment size alignment

This diff addresses the old TODO in MachOObjcopy.cpp and
correctly sets the page size used for alignment of segments.
In particular, now llvm-objcopy's output is consistent
with the input (the alignment of vmsize doesn't change).

Test plan:

1. make check-all
2. verify that a binary copied via llvm-objcopy now correctly works on iOS.

[SystemZ] Improve handling of ZERO_EXTEND_VECTOR_INREG.

Instead of doing multiple unpacks when zero extending vectors (e.g. v2i16 ->
v2i64), benchmarks have shown that it is better to do a VPERM (vector
permute) since that is only one sequential instruction on the critical path.

This patch achieves this by

1. Expand ZERO_EXTEND_VECTOR_INREG into a vector shuffle with a zero vector
   instead of (multiple) unpacks.

2. Improve SystemZ::GeneralShuffle to perform a single unpack as the last
   operation if Bytes matches it.

Fix missing build dependency on omp_gen.

`include/llvm/Frontend/OpenMP/CMakeLists.txt` creates a new target
called `omp_gen`, which is automatically added to
`LLVM_COMMON_DEPENDS` by the `add_public_tablegen_target` macro. But
it only gets added to the version of `LLVM_COMMON_DEPENDS` in the
scope of that subsidiary CMakeLists file, and it doesn't propagate all
the way back up to the permanent version of that variable which is
actually used to set dependencies.

The visible effect is that the output build scripts contain a missing
dependency. For example, if I run cmake in Ninja output mode, and then

  ninja -t commands tools/clang/examples/PrintFunctionNames/CMakeFiles/PrintFunctionNames.dir/PrintFunctionNames.cpp.o

to list all the commands that are prerequisites of building that
object file, then the list does not include the llvm-tblgen command
that builds `include/llvm/Frontend/OpenMP/`, even though that
generated include file is needed (by a chain of includes starting from
`clang/AST/AST.h`), and that object file can't be compiled without it.
This missing dependency can cause intermittent build failures,
depending on the order that Ninja (or whatever) happens to schedule
its commands.

I've fixed it by adding a `set` command in two levels of
`CMakeLists.txt` to propagate the modified version of
`LLVM_COMMON_DEPENDS` back up through the parent scopes so that
`omp_gen` does end up on the version seen by the main

[builtins] Change si_int to int in some helper declarations

This patch changes types of some integer function arguments or return values from `si_int` to the default `int` type to make it more compatible with `libgcc`.

The compiler-rt/lib/builtins/README.txt has a link to the [libgcc specification]( This specification has an explicit note on `int`, `float` and other such types being just illustrations in some cases while the actual types are expressed with machine modes.

Such usage of always-32-bit-wide integer type may lead to issues on 16-bit platforms such as MSP430. Provided [libgcc2.h](;a=blob_plain;f=libgcc/libgcc2.h;hb=HEAD) can be used as a reference for all targets supported by the libgcc, this patch fixes some existing differences in helper declarations.

This patch is expected to not change behavior at all for targets with 32-bit `int` type.

I don't at all understand why, because as far as I can see, the target
`omp_gen` is only added to `LLVM_COMMON_DEPENDS` after having been

Currently we have to override all macros that are declared. But in many
cases it is convenient to use default values and to override only
