tcg-arm: Improve scheduling of tcg_out_tlb_read

The schedule was fully serial, with no possibility for dual issue.
The old schedule had a minimal issue of 7 cycles; the new schedule
has a minimal issue of 5 cycles.

tcg-arm: Use movi32 + blx for calls on v7

Work better with branch predition when we have movw+movt,
as the size of the code is the same. Perhaps re-evaluate
when we have a proper constant pool.

tcg-arm: Use R12 for the tcg temporary

R12 is call clobbered, while R8 is call saved. This change
gives tcg one more call saved register for real data.

tcg-arm: Cleanup multiply subroutines

Make the code more readable by only having one copy of the magic
numbers, swapping registers as needed prior to that. Speed the
compiler by not applying the rd == rn avoidance for v6 or later.
