[PATCH] Fix PR 18299, ICE in gimple-lower.c


The problem is that we changing a MODIFY_EXPR, "t = t" into the DECL
"t" which is no longer gimple and so we get an ICE in gimple-lower
saying that a VAR_DECL is not handled.  This patch changes the tree
inliner to create a empty statement instead of putting the DECL
into the instruction stream.

OK? Bootstrapped and tested on ppc-darwin with no regressions.

Thanks,
Andrew Pinski

ChangeLog:

	* tree-inline.c (copy_body_r): Change "t = t" to empty
	statement instead of "t".
