[Bug tree-optimization/17506] incorrect warning about non-existant variable

[reichelt at gcc dot gnu dot org]

Confirmed. This is caused by inlining:

===================================
inline int foo (int i)
{
    if (i) return 1;
    return 0;
}

void bar()
{
    int j;
    for (; foo(j); ++j) ;
}
===================================

Compiling this with "-O1 -Wall" yields:

PR17506.c: In function `bar':
PR17506.c:3: warning: 'j' is used uninitialized in this function


Btw, Nathan, please compress files that large before attaching them to a PR.
