[PULL 01/80] tcg/i386: Set P_REXW in tcg_out_addi_ptr


From: Richard Henderson
Subject: [PULL 01/80] tcg/i386: Set P_REXW in tcg_out_addi_ptr
Date: Tue, 16 May 2023 12:40:26 -0700

The REXW bit must be set to produce a 64-bit pointer result; the
bit is disabled in 32-bit mode, so we can do this unconditionally.
