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

From: Richard Henderson
Subject: [PATCH 00/17] target/riscv: Use tcg_constant_*
Date: Thu, 8 Jul 2021 21:25:51 -0700

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.
