This patch is the initial patch for support of the AIX extended vector ABI. The extended ABI treats vector registers V20-V31 as non-volatile and we add them as callee saved registers in this patch.

Summary:
We need to handle the MCSA_LGlobal case in emitSymbolAttribute for functions marked internal in the IR so that the
appropriate storage class is emitted on the function descriptor csect. As part of this we need to make sure that external
labels are not emitted into the symbol table, so we don't emit the descriptor label in the object writing path.
