re PR middle-end/38250 (ICE with -O2 -ftree-loop-distribution)
PR middle-end/38250
* tree-loop-distribution.c (build_size_arg): New function.
(generate_memset_zero): Checks if DR_STEP(de) is NULL.
Reorganized generating of stmts.
* testsuite/gcc.dg/tree-ssa/pr38250.c: New file.
* tree-data-ref.c (dr_analyze_innermost): Returns bool.
Indicate if analysis succeed.
* tree-data-ref.h (dr_analyze_innermost): Returns bool.
* tree-predcom.c (valid_initializer_p, find_looparound_phi):
Uses new definition of dr_analyze_innermost.
