[Bug c++/23357] New: [4.1 Regression] ICE with __alignof__ on template arguments

[pinskia at gcc dot gnu dot org]

Testcase:
template<typename _Tp>
struct __per_type_pool_policy
{
  static void _S_get_pool()
  {
    const static int __align = (__alignof__(_Tp) >= 1 ? __alignof__(_Tp) : 1);
    static int _S_tune( 2 >= __align ? 1 : __align);
  }
};

This did not ICE in 4.0.0.  Also this is reduced from PR 23352 but I was trying to reduce a different ICE 
when finding with this one.

Confirmed. Similar testcase from PR 23481:

=========================================================
template<typename T> bool foo()
{
    const long int i = sizeof(T) > 1 ? sizeof(T) : 0;
    return i > 0;
}
=========================================================

This is more of the issue for a front-end person, mainly why are we calling convert_to_integer while in a 
template since that assumes all the types are set up correctly.
