find_loop_tree_blocks.  Add call to unroll_block_trees.

(identify_blocks): Handle case where no block nodes
exist.  Use xmalloc not alloca for block_vector.
(reorder_blocks): New argument top_block.  Handle case where no
block nodes exist.  Always clear BLOCK_SUBBLOCKS (block) when
adding it to the block tree.
(all_blocks): Handle case where vector is zero. Store current
block at offset 0 in vector, not n_blocks.  Don't count current
block twice in n_blocks.

(finish_struct):  If bit field is of an unsigned
type that promotes to int, promote it unsigned if traditional
or if it is the same size as int.
(start_function):  Ditto for function return value.
(finish_function): Test only can_reach_end for the warning
about reaching the end of a non-void function.
(poplevel): If apparently nested inline function has
DECL_ABSTRACT_ORIGIN, don't output it; propagate TREE_ADDRESSABLE.
(pushdecl): When copying inline details into an extern decl,
copy DECL_RESULT, TREE_ASM_WRITTEN.  Set DECL_ABSTRACT_ORIGIN.
