codingreapermapsandClaude Opus 5.5 c8662b6bca fix(agc): accept alpha-to-coverage from a 32_AR MRT0 export without a color target
radeonsi exports MRT0 as 32_AR when alpha-to-coverage is on and no color
buffer is bound, so a depth-only draw can depend on that alpha. The
decoder now accepts 32_AR and an absent MRT0 target, and reads the MRT0
export format from SPI_SHADER_COL_FORMAT, which it masked to 0 for
draws without a color target.
