Reland [clang][AIX] add option mdefault-visibility-export-mapping

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.

This relands commit: 8c8a2679a2

with fixes for the compile time and assert problems that were reported
by:

* making shouldMapVisibilityToDLLExport inline and provide an early return
in the case where no mapping is in effect (aka non-AIX platforms)
* don't try to export RTTI types which we will give internal linkage to

^^^
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.
