Seems it was missing the "/ ma + 0.5" and the order was swapped.

Should be safe to enable as all instructions seem to support 16-bit.
Unfortunately, there is no CTS test.

This patch does it as late as possible so the potential extra
basic blocks don't inhibit other optimizations.
Big thanks to Jason for writing the lowering pass.

When I implemented opt_if_loop_last_continue() I had restricted
this pass from moving other if-statements inside the branch opposite
the continue. At the time it was causing a bunch of spilling in
shader-db for i965.
However Samuel Pitoiset noticed that making this pass more aggressive
significantly improved the performance of Doom on RADV. Below are
the statistics he gathered.
28717 shaders in 14931 tests
Totals:
SGPRS: 1267317 -> 1267549 (0.02 %)
VGPRS: 896876 -> 895920 (-0.11 %)
Spilled SGPRs: 24701 -> 26367 (6.74 %)
Code Size: 48379452 -> 48507880 (0.27 %) bytes
Max Waves: 241159 -> 241190 (0.01 %)
Totals from affected shaders:
SGPRS: 23584 -> 23816 (0.98 %)
VGPRS: 25908 -> 24952 (-3.69 %)
Spilled SGPRs: 503 -> 2169 (331.21 %)
Code Size: 2471392 -> 2599820 (5.20 %) bytes
Max Waves: 586 -> 617 (5.29 %)
The codesize increases is related to Wolfenstein II it seems largely
due to an increase in phis rather than the existing jumps.
This gives +10% FPS with Doom on my Vega56.
Rhys Perry also benchmarked Doom on his VEGA64:
Before: 72.53 FPS
After: 80.77 FPS

This fixes the following LLVM error when using RADV_DEBUG=checkir:
Intrinsic name not mangled correctly for type arguments! Should be: llvm.amdgcn.buffer.atomic.add.i32
i32 (i32, <4 x i32>, i32, i32, i1)* @llvm.amdgcn.buffer.atomic.add
The cmpswap operation still uses the old intrinsic.

Especially when performing a transtion from UNDEFINED->GENERAL,
the driver shouldn't initialize HTILE metadata in compressed
state because it doesn't decompress when the src layout is
GENERAL.

I don't think we should update metadata when conditional rendering
