Michon 58eb55dddf test(recompiler): a hand-written look-back kernel instead of the game's; record the dwordx2 loads that can still tear ...

LookBackScan runs a 43-instruction decoupled look-back written for the
test: one aggregate per block, the block index from an atomic counter,
{flag, value} published with buffer_atomic_swap_x2 and read back with
glc buffer_load_dwordx2. Seven single look-backs and 50 scans of 4096
blocks are checked against a CPU prefix sum; without the recompiler
change the first whole scan fails (3 of 3 runs).

TechnicalDebt records that only glc, aligned, in-bounds dwordx2 loads
in programs with the 64-bit storage view are one atomic load: loads
without glc, and loads in programs without 64-bit buffer atomics, can
still tear against a concurrent swap_x2.
