jasonliu b98b1700ef [XCOFF] Enable symbol alias for AIX
Summary:
AIX assembly's .set directive is not usable for aliasing purpose.
We need to use extra-label-at-defintion strategy to generate symbol
aliasing on AIX.

Hubert Tong b116ded57d [AIX] Avoid structor alias; die before bad alias codegen
Summary:
`AsmPrinter::emitGlobalIndirectSymbol` is dependent on
`MCStreamer::emitAssignment` to produce `.set` directives for alias
symbols; however, the `.set` pseudo-op on AIX is documented as not
usable with external relocatable terms or expressions, which limits its
applicability in generating alias symbols.

Disable generating aliases on AIX until a different implementation
strategy is available.
