Hi Ray,

It is not possible to disable all intrinsics on 32-bit ARM, and it's not
necessarily desirable to do so for AArch64 (so I don't think it's
implemented).

Note that this is somewhat true for x86 too - leading to things like
DivU64x32 in BaseLib.

For example:
https://github.com/tianocore/edk2/blob/master/MdeModulePkg/MdeModulePkg.dsc#L172

Regards,

Leif
