Subject: PATCH [mainline] - Fix a bug with IMI in crafty

This patch fixes a bug in crafty (SPEC program) when compiling with Intermodule Analysis and
inlining. Attempt to convert an expression to a new type fails because the new type is coming
from a different translation unit.

/* header.h */

struct S {
int i1;
int i2;


#include "header.h"

int foo(struct S val)
val.i1 = 1;
val.i2 = 2;

return val.i1 + val.i2;

/* main.c */

#include "header.h"

struct S search;

extern int foo(struct S);

int main()
return foo(search);

>> gcc -c main.c foo.c -O3
main.c: In function `main':
main.c:9: error: conversion to non-scalar type requested

OK for mainline?
