re PR tree-optimization/37031 (ICE for h264ref in gather_interchange_stats with -ftree-loop-linear)
PR tree-optimization/37031
* lambda-code.c (lambda_collect_parameters): Call pointer_set_destroy
on parameter_set.
(build_access_matrix): Reserve correct size for AM_MATRIX vector,
allocate it using gc instead of heap, use VEC_quick_push instead of
VEC_safe_push.
* graphite.c (build_access_matrix): Allocate AM_MATRIX vector using gc
instead of heap, use VEC_quick_push instead of VEC_safe_push.
* tree-data-ref.h (struct access_matrix): Change matrix to gc
allocated vector from heap allocated.
* lambda.h: Add DEF_VEC_ALLOC_P for gc allocated lambda_vector.
* tree-loop-linear.c (linear_transform_loops): Allocate nest
vector only after perfect_loop_nest_depth call.
