* dwarf2out.c (dw_loc_list_node): Add force field.
(add_var_loc_to_decl): For PARM_DECL, attempt to keep
the incoming location in the list, even if it is modified
before first real insn.

(dw_loc_list): If first range of a PARM_DECL is empty,
set force flag.

* sel-sched.c (find_place_for_bookkeeping): Add new parameter
(fence_to_rewind). Use it to notice when bookkeeping will be placed
above a fence. Update comments.
(generate_bookkeeping_insn): Rewind fence when bookkeeping code is
placed just above it. Do not allow NULL place_to_insert.

(slpeel_tree_peel_loop_to_edge): Don't call
remove_dead_stmts_from_loop.
* tree-vect-loop.c (vect_determine_vectorization_factor): Don't
remove irrelevant pattern statements. For irrelevant statements
check if it is the last statement of a detected pattern, use
corresponding pattern statement instead.
(destroy_loop_vec_info): No need to remove pattern statements,
only free stmt_vec_info.
(vect_transform_loop): For irrelevant statements check if it is
the last statement of a detected pattern, use corresponding
pattern statement instead.

pattern statements. Set basic block for the new statement.
(vect_pattern_recog): Update documentation.
* tree-vect-stmts.c (vect_mark_stmts_to_be_vectorized): Scan
operands of pattern statements.
(vectorizable_call): Fix printing. In case of a pattern
statement use the lhs of the original statement when creating
a dummy statement to replace the original call.
(vect_analyze_stmt): For irrelevant statements check if it is
the last statement of a detected pattern, use corresponding
pattern statement instead.
* tree-vect-slp.c (vect_schedule_slp_instance): For pattern
statements use gsi of the original statement.
