MrFr3di 986721f5bc shader: decode FLAT, GLOBAL and SCRATCH D16 high-half loads (#1924) 
FLAT-family opcode 0x25 (FLAT/GLOBAL/SCRATCH_LOAD_SHORT_D16_HI) loads an
unsigned halfword into bits [31:16] of the destination and keeps bits [15:0].
Decode it beside the low-half variant and let it select the high half of the
existing partial destination write, so FLAT_LOAD needs no new path.

Ghost of Yotei CS 0x79b0066f0cd1f3cd stopped at
global_load_short_d16_hi v16, v18, s[0:1] offset:196 (0xdc9480c4 0x10000012).

* shader: support DS_CMPST_RTN_B32

Assassin's Creed Valhalla (PPSA01490, #281) stops on DS opcode 0x30 in a
compute shader. DS compares DATA and stores DATA2, the opposite of
BUFFER_ATOMIC_CMPSWAP, so the 32-bit atomic path swaps the two for this
opcode, as the 64-bit form does.

Deniz ŞAHİN fc86509aac shader: support DS_WRITE_B8_D16_HI (#794) 
Decode GFX10 DS opcode 0xa0 as DS_WRITE_B8_D16_HI (next to
DS_WRITE_B16_D16_HI at 0xa1) and lower it through the existing 8-bit
shared-memory write. The stored byte is bits 23:16 of the data VGPR,
selected with SDWA BYTE_2 on src1.

Add captured-instruction decode coverage (from GTA V, PPSA04264) and a
runtime regression that writes one byte of a distinctive source value
into a pre-filled LDS dword.
