Advance the memory region offset when handling a linker script data command such as BYTE or LONG. Failure to advance the offset results in corrupted output with overlapping sections. Update tests to check for this combination of both a) memory regions and b) data commands. Fixes https://bugs.llvm.org/show_bug.cgi?id=35565 Patch by Owen Shaw! llvm-svn: 321418
