For the case where baseTypeSize does not match the size of T, read the
value into a separate char buffer first. This avoids accessing buf using
two different types.
Fixes https://github.com/llvm/llvm-project/issues/94616.

Fixes a regression introduced in 91ccd8248.
The code for libompd includes kmp.h for enum kmp_sched. The dependency
to hwloc is not necessary. Avoid the dependency by skipping the
definitions in kmp.h using types from hwloc.h.
Fixes #80750

D144509 [CMake] Bumps minimum version to 3.20.0.
This partly undoes D137724.
This change has been discussed on discourse
https://discourse.llvm.org/t/rfc-upgrading-llvms-minimum-required-cmake-version/66193
Note this does not remove work-arounds for older CMake versions, that
will be done in followup patches.
D150532 [OpenMP] Compile assembly files as ASM, not C
Since CMake 3.20, CMake explicitly passes "-x c" (or equivalent)
when compiling a file which has been set as having the language
C. This behaviour change only takes place if "cmake_minimum_required"
is set to 3.20 or newer, or if the policy CMP0119 is set to new.
Attempting to compile assembly files with "-x c" fails, however
this is workarounded in many cases, as OpenMP overrides this with
"-x assembler-with-cpp", however this is only added for non-Windows
targets.
Thus, after increasing cmake_minimum_required to 3.20, this breaks
compiling the GNU assembly for Windows targets; the GNU assembly is
used for ARM and AArch64 Windows targets when building with Clang.
This patch unbreaks that.
D150688 [cmake] Set CMP0091 to fix Windows builds after the cmake_minimum_required bump
The build uses other mechanism to select the runtime.

When hwloc is used and is installed outside of the default paths, the omp CMake target
needs to provide the needed include path thru the CMake target by adding it with
target_include_directories to it, so libompd gets it as well when it defines it's cmake
target using target_link_libraries.
As suggested in D122667

This is the original patch in my GNUInstallDirs series, now last to merge as the final piece!
It arose as a new draft of D28234. I initially did the unorthodox thing of pushing to that when I wasn't the original author, but since I ended up
- Using `GNUInstallDirs`, rather than mimicking it, as the original author was hesitant to do but others requested.
- Converting all the packages, not just LLVM, effecting many more projects than LLVM itself.
I figured it was time to make a new revision.
I have used this patch series (and many back-ports) as the basis of https://github.com/NixOS/nixpkgs/pull/111487 for my distro (NixOS), which was merged last spring (2021). It looked like people were generally on board in D28234, but I make note of this here in case extra motivation is useful.
---
As pointed out in the original issue, a central tension is that LLVM already has some partial support for these sorts of things. Variables like `COMPILER_RT_INSTALL_PATH` have already been dealt with. Variables like `LLVM_LIBDIR_SUFFIX` however, will require further work, so that we may use `CMAKE_INSTALL_LIBDIR`.
These remaining items will be addressed in further patches. What is here is now rote and so we should get it out of the way before dealing more intricately with the remainder.

This is a continuation of the review: https://reviews.llvm.org/D100181
Creates a new directory "libompd" under openmp.
"TargetValue" provides operational access to the OpenMP runtime memory
for OMPD APIs.
With TargetValue, using "pointer" a user can do multiple operations
from casting, dereferencing to accessing an element for structure.
The member functions are designed to concatenate the operations that
are needed to access values from structures.
e.g., _a[6]->_b._c would read like :
TValue(ctx, "_a").cast("A",2)
.getArrayElement(6).access("_b").cast("B").access("_c")
For example:
If you have a pointer "ThreadHandle" of a running program then you can
access/retrieve "threadID" from the memory using TargetValue as below.
TValue(context, thread_handle->th) /*__kmp_threads[t]->th*/
.cast("kmp_base_info_t")
.access("th_info") /*__kmp_threads[t]->th.th_info*/
.cast("kmp_desc_t")
.access("ds") /*__kmp_threads[t]->th.th_info.ds*/
.cast("kmp_desc_base_t")
.access("ds_thread") /*__kmp_threads[t]->th.th_info.ds.ds_thread*/
.cast("kmp_thread_t")
.getRawValue(thread_id, 1);
