[ORC][MachO] __objc_imageinfo isn't a MachO "object platform section".

Commit 2666231d173 fixed a typo ("__objc_image_info" was corrected to
"__objc_imageinfo"), but this has exposed a bug where we were adding this
section to the list of platform sections to register with the ORC runtime.
The ORC runtime's MachO "object platform section" code doesn't recognize
this section (it's handled elsewhere) and errors out on it.

The solution is simply to remove __objc_imageinfo from the list of sections
to register in MachOPlatform::PlatformPlugin::registerObjectPlatformSections.

[clang] Set ShowInSystemHeader for module-build and module-import remarks

Without this change, the use of `-Rmodule-build` and `-Rmodule-import` only
produces diagnostics for modules built or imported by non-system code.

For example, if a project source file requires the Foundation module to be
built, then `-Rmodule-build` will show a single diagnostic for Foundation, but
not in turn for any of Foundation's (direct or indirect) dependencies. This is
because the locations of those transitive module builds are initiated from
system headers, which are ignored by default. When wanting to observe module
building/importing, the system modules can represent a significant amount of

`-Rmodule-build` and `-Rmodule-import` are specified.

[mlir] Use GenericAdaptor to simplify 1:N type conversion API.

For 1:N type conversion, there is a 1:N relationship between the
original operands and the converted operands. The same is true for the
results. The previous design passed an instance of a "mapping" class
into each pattern that helped with handling this 1:N correspondance.
However, this was still rather manual and, in particular, it required
the use of magic constants for the indices of the different operands.

This commits uses the generated GenericAdaptor class that is generated
for each op class in order to simplify this relationship further. The
GenericAdaptor allows to wrap around a list of arbitrary types for each
operand (via templating); for 1:N type conversion, this allows the
operand accessors of the adaptor class to return a ValueRange that
corresponds to the N values in the converted types. Patterns can thus
use the named accessors instead of magic constants, which eliminates a
common class of errors.

This commit further simplifies the API that patterns need to implement
by making the operand and result type mappings part of the adaptor.
Since many patterns only need one of the two (or even neither), this
reduces the number of unnecessary arguments in many cases.

SROA may convert a wide integer load into a narrow pointer load,
make sure we don't crash. It would not be legal to transfer the
metadata in this case.

[Orc] Add RequireDebugSections option in the DebugObjectManagerPlugin

Sometimes it's useful to be able and debug code even without actual debug info, e.g. for setting breakpoints on function names.
This patch adds a new API option to make it possible in Orc.

The existing API and behavior remains unchanged: non-debug objects are not passed to exectuors.
