Revert "[clang][AIX] add option mdefault-visibility-export-mapping"

This caused assertions, see comment on the code review:

llvm/clang/lib/AST/Decl.cpp:1510:
clang::LinkageInfo clang::LinkageComputer::getLVForDecl(const clang::NamedDecl *, clang::LVComputationKind):
Assertion `D->getCachedLinkage() == LV.getLinkage()' failed.

> The option mdefault-visibility-export-mapping is created to allow
> mapping default visibility to an explicit shared library export
> (e.g. dllexport). Exactly how and if this is manifested is target
> dependent (since it depends on how they map dllexport in the IR).
>
> Three values are provided for the option:
>
> * none: the default and behavior without the option, no additional export linkage information is created.
> * explicit: add the export for entities with explict default visibility from the source, including RTTI
> * all: add the export for all entities with default visibility
>
> This option is useful for targets which do not export symbols as part of
> their usual default linkage behaviour (e.g. AIX), such targets
> traditionally specified such information in external files (e.g. export
> lists), but this mapping allows them to use the visibility information
> typically used for this purpose on other (e.g. ELF) platforms.

AIX
^^^
The ``-mdefault-visibility-export-mapping=`` option can be used to control
mapping of default visibility to an explicit shared object export
(i.e. XCOFF exported visibility). Three values are provided for the option:
* ``-mdefault-visibility-export-mapping=none``: no additional export
information is created for entities with default visibility.
* ``-mdefault-visibility-export-mapping=explicit``: mark entities for export
if they have explict (e.g. via an attribute) default visibility from the
source, including RTTI.
* ``-mdefault-visibility-export-mapping=all``: set XCOFF exported visibility
for all entities with default visibility from any source. This gives a
export behavior similar to ELF platforms where all entities with default
visibility are exported.
