[PULL 03/10] tcg: Optimize inline dup_const for MO_64


From: Richard Henderson
Subject: [PULL 03/10] tcg: Optimize inline dup_const for MO_64
Date: Sat, 23 Jan 2021 08:50:13 -1000

Avoid the out-of-line function call for immediate MO_64.
In addition, diagnose all invalid constants at compile-time.
