  Log Message:
  -----------
  [ELF] -M/-Map: fix VMA/LMA/Size columns of symbol assignments when address/size>=2**32

SymbolAssignment::addr stores the location counter. The type should be
uint64_t instead of unsigned. The upper half of the address space is
commonly used by operating system kernels.

Similarly, SymbolAssignment::size should be an uint64_t. A kernel linker
script can move the location counter from 0 to the upper half of the
address space.
