Subject: [PATCH] inline fail reporting: reporting inline fail caused by overwritable function

When inline failed because of callee is overwritable, gcc will not report it 
in dump file as other inline failing cases do. This patch correct this.

ChangeLog:
2013-04-05  Zhouyi Zhou	<yizhouzhou@ict.ac.cn>

	    * cif-code.def: correct the comment for overwritable function
	    * ipa-inline.c: let dump mechanism report the inline fail caused by 
		overwritable function
