Subject: [PATCH 150/157] [Backport][SME] Add operator* to gimple_stmt_iterator
 and gphi_iterator

Reference: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=c39cdd9e654540f74cd2478019c40f1611554a44

This allows STL style iterator dereference.  It's the same
as gsi_stmt () or .phi ().

	* gimple-iterator.h (gimple_stmt_iterator::operator*): Add.
	(gphi_iterator::operator*): Likewise.
