Restrict what kind of statements are used for auto-profile

When building profile of walk_tree_1 during autoprofiledbootstrap we produce
non-zero counts to call of tree_check_failed because location of INLINE_ENTRY
debug statement is misplaced.  Auto-profile already knows it should skip
clobbers since their locations will never go into debug info.  This patch extend
it to all kind of debug statement except for DEBUG_BEGIN_STMT, nops, labels
and predict.
