UefiCpuPkg/CpuDxe: consider freed-memory guard in non-stop mode
Non-stop mode was introduced / explained in commit 8f2613628acf
("MdeModulePkg/MdeModulePkg.dec: add new settings for PCDs",
2018-08-30).
The macro HEAP_GUARD_NONSTOP_MODE was added to CpuDxe in commit
dcc026217fdc ("UefiCpuPkg/CpuDxe: implement non-stop mode for uefi",
2018-08-30).
Another instance of the macro HEAP_GUARD_NONSTOP_MODE was added to
PiSmmCpuDxeSmm -- with BIT1|BIT0 replaced with BIT3|BIT2 -- in commit
09afd9a42a7f ("UefiCpuPkg/PiSmmCpuDxeSmm: implement non-stop mode for
SMM", 2018-08-30)
Since the freed-memory guard is for UEFI-only. This patch only updates
HEAP_GUARD_NONSTOP_MODE in "UefiCpuPkg/CpuDxe/CpuDxe.h" (add BIT4).
