Hi,
sorry for the noise.  This patch fixes -fno-use-linker-plugin for me and
also removes the extra dg-do I forgot in alias_3-1.c

	* alias-1_0.C: Use -O3.
	* alias-2_0.C: Use -O3.
	* alias-3_0.C: Add loop to enable inlining with -fno-use-linker-plugin.
	* alias-3_1.C: Remove dg-lto-do and dg-lto-options.
