Remove unneeded __sync_* library functions from the kernel.

Aggressively randomize the location of the stack on all 64-bit architectures except alpha. This will put the stack at a random location in the upper 1/4th of the userland virtual address space providing up to 26 additional bits of randomness in the address. Skip alpha for now since it currently puts the stack at a (for a 64-bit architecture) very low address. Skip 32-bit architectures for now as well since those have a much smaller virtual address space and we need more time to figure out what a safe amount of extra randomizations is. These architectures will continue to use a mildly randomized stack address through the existing stackgap random mechanism. We will revisit this after 7.3 is released.
