[PATCH for-7.2] accel/tcg: Suppress compiler warning with flag -Wclobber

From: Stefan Weil
Subject: [PATCH for-7.2] accel/tcg: Suppress compiler warning with flag -Wclobbered
Date: Sat, 5 Nov 2022 12:44:24 +0100

At least some versions of gcc show a warning when compiler flag -Wclobbered
is used (tested with gcc on Debian bookworm i386 and with cross gcc for
Windows on Debian bullseye).
