Cygwin: move x86_64 thread stack area
The x86_64 thread stack area collides with the share user data in
recent versions of Windows. Let's get ourselvels get out of the
way and move the thread stack area in the former slack space
between DLL area and heap, from 0x6:00000000 to 0x8:00000000.
That quadruplicates the stack area, so allow bigger maximum stack
sizes.
