updateGsCsrFieldForVSync runs on the detached vsync worker and updated the
FIELD bit with a non-atomic read-modify-write of GSRegisters::csr while
guest threads concurrently read/write the same word (MMIO read32/read64 and
the W1C handling in write32/write64) and the GIF path sets SIGNAL/FINISH.
Even though the writers touch disjoint bits, a whole-word RMW loses the
other side's update: a clobbered SIGNAL/FINISH set hangs a game
synchronizing on GS completion, a clobbered W1C clear re-asserts a handled
interrupt, and a clobbered FIELD toggle stalls interlace field polling.
ThreadSanitizer flags the race on main (updateGsCsrFieldForVSync vs
PS2Memory::write64 and GS::writeRegister).
Make the field std::atomic<uint64_t> and perform every update as a single
atomic RMW:
- vsync FIELD toggle -> fetch_or / fetch_and
- MMIO W1C writes -> compare_exchange loop in shared helpers (a
load-then-store pair would still race); a 32-bit store to the CSR's upper
dword previously bypassed the W1C special case entirely and went through
the plain merge branch - both halves now share the same atomic helper
with unchanged guest-visible semantics
- GIF SIGNAL/FINISH -> fetch_or
- reads -> load()
std::atomic<uint64_t> is lock-free on all supported targets (static_assert
added), the struct's size/alignment asserts are unchanged, GSRegisters is
never copied by value, and default (seq_cst) ordering is used throughout -
these operations are rare (vblank ticks, GIF signals, CSR MMIO), so
reviewability wins over micro-optimization.
New regression test: two racer threads each own one status bit (SIGNAL /
FINISH) and loop 80k GIF-set + W1C-clear cycles verifying their own bit
after each half-op while the vsync worker toggles FIELD. Fails 20/20 runs
against the previous code, passes 50/50 with the fix, ~350ms runtime, no
sanitizer needed.

* [runtime] Memory swizzling rework
Reimplementation of memory swizzling supporting all valid GS texture
storage types.
An additional optimization was done to improve the speed of lookups.
Since page access is linear, we can precompute the non-linear bit
(blocks and columns) for an entire page for each format. This reduces
the runtime calculation to just calculating the correct page in 2d
memory space and then performing a lookup in the table to get the
location in memory inside a page. Since all page accesses are the same,
this works across all pages. Speed improvements should be compounded by
the number of accesses but there might be some reductions as a result of
actually implementing formats that were not implemented before.
I took care to do this with simple math. GS swizzling is complicated and
optimizing it for debug builds is outside the scope of my current work.
This is just the standalone code. It will be worked into the current
rasterizer in a follow up commit.
