Merge tag 'pull-tcg-20250117' of https://gitlab.com/rth7680/qemu into staging
tcg:
  - Add TCGOP_TYPE, TCGOP_FLAGS.
  - Pass type and flags to tcg_op_supported, tcg_target_op_def.
  - Split out tcg-target-has.h and unexport from tcg.h.
  - Reorg constraint processing; constify TCGOpDef.
  - Make extract, sextract, deposit opcodes mandatory.
  - Merge ext{8,16,32}{s,u} opcodes into {s}extract.
tcg/mips: Expand bswap unconditionally
tcg/riscv: Use SRAIW, SRLIW for {s}extract_i64
tcg/riscv: Use BEXTI for single-bit extractions
tcg/sparc64: Use SRA, SRL for {s}extract_i64

disas/riscv: Guard dec->cfg dereference for host disassemble
util/cpuinfo-riscv: Detect Zbs
accel/tcg: Call tcg_tb_insert() for one-insn TBs
linux-user: Add missing /proc/cpuinfo fields for sparc
