[PATCH 4/4][MSP430] Define symbols to initialise high data and high bss when the upper data region could be used


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.
