[Mechanical Patch ARM/AArch64 1/2] Rename load/store scheduling types to encode data size

In the AArch64 backend and scheduling models there is some confusion as to
what the load1/load2 etc. scheduling types refer to. This leads to us using
load1/load2 in two contexts - for a variety of 32-bit, 64-bit and 128-bit
loads in AArch32 and 128-bit loads in AArch64. That leads to an undesirable
confusion in scheduling.

Fixing it is easy, but mechanical and boring. Essentially,

  s/load1/load_4/
  s/load2/load_8/
  s/load3/load_12/
  s/load4/load_16/
  s/store1/store_4/
  s/store2/store_8/
  s/store3/store_12/
  s/store4/store_16/

Across all sorts of pipeline models, and the two backends.

I have intentionally not modified any of the patterns which now look obviously
incorrect. I'll be doing a second pass over the AArch64 back-end in patch
2/2 which will fix these bugs.
