[lldb] Explicitly use the configuration architecture when building test executables
The Darwin builder currently assumes in `getArchCFlags` that the passed `arch`
value is an actual string it can string.join with vendor/os/version/env strings:
```
triple = '-'.join([arch, vendor, os, version, env])
```
However this is not true for most tests as we just pass down the `arch=None`
default value from `TestBase.build`. This causes that if we actually end up in
this function we just error out when concatenating `None` with the other actual
strings of vendor/os/version/env. What we should do instead is check that if
there is no test-specific architecture that we fall back to the configuration's
architecture value.
It seems we already worked around this in `builder.getArchSpec` by explicitly
falling back to the architecture specified in the configuration.
This patch just moves this fallback logic to the top `build` function so that it
affects all functions called from `TestBase.build`.

[sanitizer] Convert PrintModuleMap to DumpProcessMap
As discussed in the review for D87120 (specifically at
https://reviews.llvm.org/D87120#inline-831939), clean up PrintModuleMap
and DumpProcessMap usage differences. The former is only implemented for
Mac OSX, whereas the latter is implemented for all OSes. The former is
called by asan and tsan, and the latter by hwasan and now memprof, under
the same option. Simply rename the PrintModuleMap implementation for Mac
to DumpProcessMap, remove other empty PrintModuleMap implementations,
and convert asan/tsan to new name. The existing posix DumpProcessMap is
disabled for SANITIZER_MAC.

[mlir][shape] Split out structural type conversions for shape dialect.
A "structural" type conversion is one where the underlying ops are
completely agnostic to the actual types involved and simply need to update
their types. An example of this is shape.assuming -- the shape.assuming op
and the corresponding shape.assuming_yield op need to update their types
accordingly to the TypeConverter, but otherwise don't care what type
conversions are happening.
Also, the previous conversion code would not correctly materialize
conversions for the shape.assuming_yield op. This should have caused a
verification failure, but shape.assuming's verifier wasn't calling
RegionBranchOpInterface::verifyTypes (which for reasons can't be called
automatically as part of the trait verification, and requires being
called manually). This patch also adds that verification.

[CostModel] remove cost-kind predicate for scatter/gather cost
This is similar in spirit to
01ea93d85d6e (memcpy) except that
here the underlying caller assumptions were created for vectorizer
use (throughput) rather than other passes.
That meant ARM could have an enormous throughput cost with no
corresponding size, latency, or blended cost increase. X86 has
the same throughput restriction as the basic implementation, so
it is still unchanged.
Paraphrasing from the previous commit:
This may not make sense for some callers, but at least now the
costs will be consistently wrong instead of mysteriously wrong.
Targets should provide better overrides if the current modeling
is not accurate.

This is to permit reliably #including files from the LLVM tree in libomptarget,

for the first example of removing duplication given this new requirement.
The weekly openmp dev call reached consensus on this approach. See also D87841
for some alternatives that were considered. In the future, we may want to
introduce a new top level repo for shared constants, or start using the ADT
library within openmp.
This will break sufficiently exotic build systems, trivial fixes as below.
Building libomptarget as part of the monorepo will continue to work.
If openmp is built separately, it now requires a cmake macro indicating
where to find the LLVM source tree.
If openmp is built separately, without the llvm source tree already on disk,
