    [lld-macho] Ignore local personality symbols if non-local with the same name exisst,  to avoid "too many personalities" error.

    Sometimes people intentionally re-define a dylib personlity symbol as a local defined symbol as a workaround to a ld -r bug.
    As a result, we could see "too many personalities" to encode. This patch tries to handle this case by ignoring the local symbols entirely.

The third-party ittnotify sources updated from https://github.com/intel/ittapi.
Changes applied:
- llvm license aded to all files; initial BSD license saved in LICENSE.txt;
- clang-formatted;
- renamed *.c to *.cpp, similar to what we did with all our sources;
- added #include "kmp_config.h" with definition of INTEL_ITTNOTIFY_PREFIX macro
  into ittnotify_static.cpp.

The intrinsic inquiry functions SIZE and UBOUND -- but not LBOUND --

[X86] Improve `matchBinaryShuffle()`'s `BLEND` lowering with per-element all-zero/all-ones knowledge

We can use `OR` instead of `BLEND` if either the element we are not picking is zero (or masked away);
or the element we are picking overwhelms (e.g. it's all-ones) whatever the element we are not picking:

This patch implements the following semantic checks according to
OpenMP Version 5.1 Ordered construct restriction:

```
At most one threads clause can appear on an ordered construct; At most
one simd clause can appear on an ordered construct; At most one
depend(source) clause can appear on an ordered construct; Either
depend(sink:vec) clauses or depend(source) clauses may appear on an
ordered construct, but not both.
```

This patch also implements the following semantic checks according to
the syntax and descriptions in OpenMP Version 5.1 Ordered construct:

```
The dependence types of sink or source are only allowed on an ordered
construct. The depend(*) clauses are not allowed when ordered construct
is a block construct with an ordered region. The threads or simd clauses
are not allowed when the ordered construct is a standalone construct
with no ordered region.
```

Seemingly, names in anonymous namespaces are ALWAYS given the unique
internal linkage name on windows, and I was not aware of this when I put
the names in my test!  Replaced them with a wildcard.

Adds support for a feature macro `__opencl_c_read_write_images` in
C++ for OpenCL 2021 enabling a respective optional core feature
from OpenCL 3.0.

This change aims to achieve compatibility between C++ for OpenCL
2021 and OpenCL 3.0.

We previously made all multiversioning resolvers/ifuncs have weak
ODR linkage in IR, since we NEED to emit the whole resolver every time
we see a call, but it is not necessarily the place where all the
definitions live.

HOWEVER, when doing so, we neglected the case where the versions have
internal linkage.  This patch ensures we do this, so you don't get weird
behavior with static functions.

Fix parameter name typos and drop returns statements from void functions

The MMX pack/unpck shuffles don't need an override - they have the same behaviour as other shuffles (Port0 only).
The SSE pslldq/psrldq shuffles don't need an override - they have the same behaviour as other shuffles (Port0 only).
The SSE pshufb shuffles use 4uops (+1 load).

Noticed the pslldq/psrldq issue while trying to improve reduction costs via the D103695 helper script, and fixed the others while reviewing. Confirmed with Intel AoM / Agner / InstLatX64.

Rework getConstantstVRegValWithLookThrough in order to make it clear if we
are matching integer/float constant only or any constant(default).
Add helper functions that get DefVReg and APInt/APFloat from constant instr
getIConstantVRegValWithLookThrough: integer constant, only G_CONSTANT
getFConstantVRegValWithLookThrough: float constant, only G_FCONSTANT
getAnyConstantVRegValWithLookThrough: either G_CONSTANT or G_FCONSTANT

Rename getConstantVRegVal and getConstantVRegSExtVal to getIConstantVRegVal
and getIConstantVRegSExtVal. These now only match G_CONSTANT as described
in comment.

Relevant matchers now return both DefVReg and APInt/APFloat.

Replace existing uses of getConstantstVRegValWithLookThrough and
getConstantVRegVal with new helper functions. Any constant match is
only required in:
ConstantFoldBinOp: for constant argument that was bit-cast of float to int
getAArch64VectorSplat: AArch64::G_DUP operands can be any constant
amdgpu select for G_BUILD_VECTOR_TRUNC: operands can be any constant

In other places use integer only constant match.
