score: Move Thread_Control::Registers member
Place this member placed directly after the end of the common block so that
the structure offsets are as small as possible. This helps on instruction
set architectures with a very limited range for intermediate values. For
example, see the __aeabi_read_tp() implementation for ARM Thumb-1.
Update #3835.
