Remove assumption that the transition code for transitioning from 64-bit to 32-bit mode is 64 bytes. Instead compute the size based on the implementation in the ASM file.
...
Update logic to align new 32-bit stack on a 4 byte boundary
Update logic to prevent one slot overlap between the transition code and the new stack.

Save label "@F" to 64-bit register (r10) instead of 32-bit register (eax) in case label @F is above 4G.
