RFR (XL): 8023038: PPC64 (part 15): Platform files for AIX/PPC64 support

[Volker Simonis]

Hi all (sorry, the first mail was only sent to ppc-aix-port-dev),

this change finally contains the basic AIX platform source files:

http://cr.openjdk.java.net/~simonis/webrevs/8023038

Together with the previous change ("8023034: PPC64 (part 14):
Implement AIX/PPC64 support in HotSpot makefiles") it enables the
build of an interpreter-only HotSpot VM on AIX. Assuming you have xlC
and the needed tools like GNU make in your path you can build it with
the following command line from within the hotspot/make directory:

make ALT_BOOTDIR=<j2sdk-image> ALT_OUTPUTDIR=/tmp/stage-opt-core/
ARCH_DATA_MODEL=64 VERBOSE=true CC_INTERP=true OPENJDK=true
HOTSPOT_BUILD_JOBS=8 JVM_VARIANT_CORE=true all_productcore

Notice that although this change is flagged 'XL' it only contains
platform dependent files in 'src/os/aix/', 'src/os_cpu/aix_ppc' and
'src/share/vm/utilities/globalDefinitions_xlc.hpp' and doesn't affect
the current Oracle platforms at all.

Thank you and best regards,
Volker
