testsuite: Add -fno-short-enums to pr97315-1.C

The test case assumes that sizeof(tree_code) >= 2. On some targets, like
Cortex-M on arm-none-eabi, -fshort-enums is enabled by default and in
that case, sizeof(tree_code) will be 1 and the following warning is
emitted:

.../pr97315-1.C:8:13: warning: width of 'tree_base::code' exceeds its type

Avoid the warning by forcing -fno-short-enums.

gcc/testsuite/ChangeLog:

	* g++.dg/opt/pr97315-1.C: Add -fno-short-enums.
