re PR debug/48159 (ICE: SIGSEGV in build2_stat (tree.c:3802) with -ftree-loop-distribution -g)
PR debug/48159
* tree-ssa.c (reset_debug_uses): New function.
* tree-flow.h (reset_debug_uses): New prototype.
* tree-data-ref.c (stmts_from_loop): Ignore debug stmts.
* tree-loop-distribution.c (generate_loops_for_partition): Call
reset_debug_uses on the stmts that will be removed. Keep around
all debug stmts, don't count them as bits in partition bitmap.
(generate_builtin): Don't count debug stmts or labels as bits in
partition bitmap.
* gcc.dg/pr48159-1.c: New test.
* gcc.dg/pr48159-2.c: New test.
