Message:

sparc64 work.

• the syscall wrapper needs to use the "memory" clobber specifier to prevent over-optimization.
• on sparc64, the user address space spans the whole 64-bit space and therefore the macro USER_ADDRESS_SPACE_SIZE_ARCH, as it was defined, overflows to 0
• stop using USER_ADDRESS_SPACE_SIZE_ARCH and define MAX_HEAP_SIZE instead
• in our situation when kernel and user address spaces are separate, the G (global) bit cannot be used (there is no point in it anymore)
• add the DEBUG() macro to stdio.h; DEBUG() uses SYS_IO and is a good debugging tool for getting early userspace to work
