[svn r76] Fixed: TypeInfo for structs. Fixed: PostExp was unable to allocate storage for parameters. Fixed: Many types of functions and delegates were broken. Misc cleanups.

char[] func(void* p)
{
    return null;
}

void main()
{
    char[] function(void*) fp = &func;
    assert(fp(null) is null);
