AIX: Export symbols from IBMClang IPA objects
When interprocedural analysis is enabled on the IBMClang family of
compilers (via the `-flto` option) then the resulting object files
contain LLVM IR rather than XCOFF objects[1].
ExportImportList needs to detect LLVM IR objects and use the
`ibm-llvm-nm` tool that ships with the compiler to create the extract
the defined symbols.
Without this change, such objects result in an error message from
`dump` and no symbols being exported from the object file.
