This patch adds functionality to gas to define symbols for initialising high data and high bss, when -mdata-region is used with the "either" or "upper" parameters. Since the linker can now create upper and either sections even when none exist at assembly time, the current behaviour of only defining these symbols when .upper or .either sections exist was not enough. The parameter passed to GCC for -mdata-region is propagated to the assembler using this option. The added tests pass when built with todays GCC trunk and binutils master.
