[X86] Use EVT::getVectorVT instead of changeVectorElementType in reduceVMULWidth.

Changing vector element type doesn't work for v6i32->v6i16 now
that v6i32 is an MVT and v6i16 is not.

I would like to fix this in changeVectorElementType, but you
need a LLVMContext to call getVectorVT which we can't get from
an MVT.

Fixes PR50709.

[AMDGPU][Libomptarget] Drop dead code related to g_atl_machine

This patch includes some changes which deletes the code accessing
g_atl_machine global. Some accesses related to memory_pools are
still remaining.

[ORC-RT] Fix void function handling in the WrapperFunction utility.

Handlers returning void previously caused compile errors. Fix that by
substituting SPSEmpty placeholder values.

[Debug-Info][CodeView] Fix GUID string generation for MSVC generated objects.

This patch is to address
  YAML:455:28: error: GUID strings are 38 characters long

where X is a hex digit (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F).
The length of the individual components must be: 8, 4, 4, 4, 12.

For some cases, the converted string generated by obj2yaml, does not
comply with those lengths. yaml2obj checks that the GUID string must
be 38 characters including the dashes and braces.

Support buffers in LinalgFoldUnitExtentDims

This doesn't add any canonicalizations, but executes the same
simplification on bufferSemantic linalg.generic ops by using
linalg::ReshapeOp instead of linalg::TensorReshapeOp.

[libc] Add a set of elementary operations

Resubmission of D100646 now making sure that we handle cases were `__builtin_memcpy_inline` is not available.

Original commit message:
Each of these elementary operations can be assembled to support higher order constructs (Overlapping access, Loop, Aligned Loop).
The patch does not compile yet as it depends on other ones (D100571, D100631) but it allows to get the conversation started.
