[pushed] coroutines: Partial reversion of r11-437-g5ef067eb14d4.

[Iain Sandoe]

Hi

I got a bit over-zealous in the attempt to make better use of the higher-
level APIs in the c++ FE,  this reverts that part of the change,

Tested on x86_64-darwin,
applied to master,
thanks
Iain

====

co_returns are statements, not expressions; they do not need
to be wrapped in an EXPR_STMT.

gcc/cp/ChangeLog:

	* coroutines.cc (finish_co_return_stmt): Revert change to use
	finish_expr_stmt.
