PR debug/36617
* tree-cfg.c (struct move_stmt_d): Replace block field with
orig_block and new_block fields.
(move_stmt_r): Only set TREE_BLOCK to p->new_block if
if it used to be NULL, p->orig_block or if p->orig_block is NULL.
(move_block_to_fn): Replace vars_map and new_label_map arguments
with struct move_stmt_d pointer.
(replace_block_vars_by_duplicates): New function.
(move_sese_region_to_fn): Add ORIG_BLOCK argument.  Adjust
move_block_to_fn caller.  If ORIG_BLOCK is non-NULL, move over
all subblocks of ORIG_BLOCK to the new function.  Call
replace_block_vars_by_duplicates.
* tree-flow.h (move_sese_region_to_fn): Adjust prototype.
* omp-low.c (expand_omp_taskreg): Set TREE_USED on DECL_INITIAL
BLOCK of the new function.  Adjust move_sese_region_to_fn caller.
Prune vars with original DECL_CONTEXT from child_cfun->local_decls.
(expand_omp): Temporarily set input_location to the location of
region's controlling stmt.
(lower_omp_sections, lower_omp_for): Add a BLOCK into outermost
BIND_EXPR, push ctx->block_vars and gimplification vars into
the BIND_EXPR and its block's BLOCK_VARS instead of directly
into dest function.
(lower_omp_single): Set TREE_USED on the BIND_EXPR's BLOCK if
there are any BLOCK_VARS.
(lower_omp_taskreg): Set BLOCK on a BIND_EXPR containing the
OMP_PARALLEL or OMP_TASK stmt.
(lower_omp): Save and restore input_location around the lower_omp_1
call.

* testsuite/libgomp.c/debug-1.c: New test.
