  • Stack should be aligned to 16 bytes
  • UEFI shadow stack space should be 32 bytes even for functions with less than 4 arguments
  • Non-volatile registers must be restored before the program exist

aarch64: Add remaining GAS-style defines
d5c4f0d 
Note that XOR_X0_X1_X0 is actually eor_x0,x0,x1, this is not a typo.

There is also an additional mov_x8,177 because sys_getgid is 176, but
the define names it egid. egid is 177.
