If you had the register alias feature I described above, would you be ale
to write such low-level manipulations using intrinsics?
I think I would be able to rewrite all x86 asm blocks I've ever written
using that feature.

ARM and PPC both have unique features relating to their branch control and
branch prediction that x86 doesn't have. Sadly, all high level languages
COMPLETELY overlook such features when designing high level expressions,
because they are traditionally designed for x86 first.
A thorough set of intrinsics can allow access to these features though,
although since they're related to branch control/conditional execution, it
feels clumsy, since you lose the feeling of structured code; ie, no scoped
if blocks, loop constructs, etc,  if you have to use intrinsics to generate
conditions or masks.

ARM is the most common architecture on earth now. It would be nice if D
were able to take better advantage of the architecture.
