Patch committed: Rename structs in expr.c

[Ian Lance Taylor <iant at google dot com>]

This patch is originally due to JÃrn Rennecke.  The structs
move_by_pieces and store_by_pieces in expr.c can be confusing when
compiling with C++, because there are also functions with those names.
Recall that in C++ the name of a struct can be used directly without the
"struct" declarator.  Gdb can get confused as to what the names refer
to.  This patch renames the structs by adding a _d suffix.

Bootstrapped on x86_64-unknown-linux-gnu.  Committed.

	* expr.c (struct move_by_pieces_d): Rename from move_by_pieces.
	Change all uses.
	(struct store_by_pieces_d): Rename from store_by_pieces.  Change
	call uses.
