Fix bugs relating to flexibly-sized objects in nios2 backend.
PR target/92499
gcc/c/
* c-decl.c (flexible_array_type_p): Move to common code.
gcc/
* config/nios2/nios2.c (nios2_in_small_data_p): Do not consider
objects of flexible types to be small if they have internal linkage
or are declared extern.
* config/nios2/nios2.h (ASM_OUTPUT_ALIGNED_LOCAL): Replace with...
(ASM_OUTPUT_ALIGNED_DECL_LOCAL): ...this. Use targetm.in_small_data_p
instead of the size of the object initializer.
* tree.c (flexible_array_type_p): Move from C front end, and
generalize to handle fields in non-C structures.
* tree.h (flexible_array_type_p): Declare.
gcc/testsuite/
* gcc.target/nios2/pr92499-1.c: New.
* gcc.target/nios2/pr92499-2.c: New.
