ChadandClaude Opus 5.5 d78eea1f5f feat(shader): implement the 64-bit LDS atomics ...

ds_add/sub/rsub/inc/dec_u64, ds_min/max_i64/u64, ds_and/or/xor/mskor_b64,
ds_cmpst_b64/f64, ds_min/max_f64, their _rtn forms and ds_wrxchg_rtn_b64
threw in the decoder.

LDS is a 32-bit workgroup array, so the two dwords are read and written
under a lock dword placed after the guest LDS, which is cleared with a
workgroup barrier at entry. The lock is acquired and released in the same
loop iteration, so lanes of one subgroup cannot deadlock on it. Stages
whose LDS is a function variable update it directly. 64-bit GDS atomics
throw.
