This PR contains initial changes for building and testing libomp on AIX. More changes will follow. - `KMP_OS_AIX` is defined for the AIX platform - `KMP_ARCH_PPC` is defined for 32-bit PPC - `KMP_ARCH_PPC_XCOFF` and `KMP_ARCH_PPC64_XCOFF` are for 32- and 64-bit XCOFF object formats respectively - Assembly file `z_AIX_asm.S` is used for AIX specific assembly code and will be added in a separate PR - The target library is disabled because AIX does not have the device support - OMPT is temporarily disabled
