When building with GCC 10.2 configured with --extra-cflags=-Os, we get:
target/arm/m_helper.c: In function ‘arm_v7m_cpu_do_interrupt’:
target/arm/m_helper.c:1811:16: error: ‘restore_s16_s31’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
1811 | if (restore_s16_s31) {
| ^
target/arm/m_helper.c:1350:10: note: ‘restore_s16_s31’ was declared here
1350 | bool restore_s16_s31;
| ^~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
Initialize the 'restore_s16_s31' variable to silence the warning.
