[OpenMP][2/2]  Make device functions have hidden visibility

Similar to https://reviews.llvm.org/D136111, this time for class
methods.

D136111 summary:

In OpenMP target offloading an in other offloading languages, we
maintain a difference between device functions and kernel functions.
Kernel functions must be visible to the host and act as the entry point
to the target device. Device functions however cannot be called directly
by the host and must be called by a kernel function. Currently, we make
all definitions on the device protected by default. Because device
functions cannot be called or used by the host they should have hidden
visibility. This allows for the definitions to be better optimized via
LTO or other passes.

This patch marks every device class methods in the AST as having hidden
visibility. The kernel function is generated later at code-gen and we
set its visibility explicitly so it should not be affected. This
prevents the user from overriding the visibility, but since the user
can't do anything with these symbols anyway there is no point exporting
them right now.

[InstCombine] Convert some tests to opaque pointers (NFC)

These involved regenerating test checks. There are two significant
differences here:

1. With typed pointers we sometimes swapped gep and addrspacecast,
   as a side-effect of other transforms. However, the current
   direction is likely undesirable, and we should canonicalize in
   the reverse direction instead (gep of ac, instead of ac of gep).
   This should be done after typed pointers are removed, to avoid
   conflicting transforms.

2. The "descaling" optimization isn't really compatible with
   opaque pointers. This will be addressed longer-term by moving
   away from type-based GEP, at which point the form with explicit
   multiplications will be the canonical one.

of LLVM IR instruction-level metadata extensible. It extends the
signature of the existing dialect interface to provide a method to
import specific metadata kinds and attach them to the imported
operation. The conversion function can rely on the ModuleImport class
to perform support tasks.

The revision implements the second part of the
"extensible llvm ir import" rfc:
https://discourse.llvm.org/t/rfc-extensible-llvm-ir-import/67256/6

The interface method names changed a bit compared to the suggested
design. The hook to set the instruction level metadata is now called
setMetadataAttrs and takes the metadata kind as an additional parameter.
We do not hand in the original LLVM IR instruction since it is not used
at this point. Importing named module-level meta data can be added in a
later stage after gaining some experience with this extension mechanism.
