commit 94b1fb81dd8f3db24b6db5476bbaa60db81014bd
Author: Christoph Müllner

[1/3] expr: Export clear_by_pieces()

Make clear_by_pieces() available to other parts of the compiler,
similar to store_by_pieces().

gcc/ChangeLog:

* expr.cc (clear_by_pieces): Remove static from clear_by_pieces.
* expr.h (clear_by_pieces): Add prototype for clear_by_pieces.

(cherry picked from commit e6e41b68fd805ab126895a20bb9670442b198f62)
