[PATCH 00/17] target/riscv: Use tcg_constant_*

[Richard Henderson]

Replace use of tcg_const_*, which makes a copy into a temp
which must be freed, with direct use of the constant.

Reorg handling of $zero, with different accessors for
source and destination.

Reorg handling of csrs, passing the actual write_mask
instead of a regno.

Use more helpers for RVH expansion.
