RFR: 8324834: Use _LARGE_FILES on AIX [v3]

[Magnus Ihse Bursie]

> In the same spirit as [JDK-8318696](https://bugs.openjdk.org/browse/JDK-8318696), we should adapt the AIX-specific code in hotspot so it uses the well-defined posix `<foo>` functions, instead of `<foo>64`. By setting the define _LARGE_FILES, this will make `<foo>` behave as `<foo>64`, just as _FILE_OFFSET_BITS=64 does on gcc. (Reference: https://www.ibm.com/docs/en/aix/7.1?topic=volumes-writing-programs-that-access-large-files)
> 
> In theory, it should not even be necessary to set this, since we only compile for 64-bit AIX platforms, and this is only relevant on 32-bit platforms. But let's add the define anyway, for good measure. It shows at least that we have thought about the matter. :-)
> 
> I have not been able to test this on AIX. I hope someone with AIX access can take this for a spin.
> 
> The reason I'm doing this is for [JDK-8324539](https://bugs.openjdk.org/browse/JDK-8324539). After both these bugs are fixed, there will be no more `<foo>64` function calls in the code base.
