e726f65867 tcg: Remove TCG_TARGET_HAS_{br,set}cond2 from riscv and loongarch64
These defines never should have been added as they were
never used.  Only 32-bit hosts may have these opcodes and
they have them unconditionally.

Fixes: 6cb14e4de29 ("tcg/loongarch64: Add the tcg-target.h file")
Fixes: fb1f70f3685 ("tcg/riscv: Add the tcg-target.h file")

6482e9d2a4 tcg: Remove TCG_TARGET_HAS_deposit_{i32,i64}
Make deposit "unconditional" in the sense that the opcode is
always present.  Rely instead on TCG_TARGET_deposit_valid,
now always defined.

841e2c5257 tcg/riscv64: Fold the ext{8,16,32}[us] cases into {s}extract
Accept byte and word extensions with the extract opcodes.
This is preparatory to removing the specialized extracts.
