Variable LONG_TYPE_SIZE and MAX_LONG_TYPE_SIZE

["H . J . Lu" <hjl at lucon dot org>]

On mips, LONG_TYPE_SIZE and MAX_LONG_TYPE_SIZE are defined as

#define LONG_TYPE_SIZE (TARGET_LONG64 ? 64 : 32)
#define MAX_LONG_TYPE_SIZE 64

As the result, HOST_WIDE_INT is defined as "long long" when configured
for a mips target. For the 32bit mips target, I got the preprocessed
code like:

typedef unsigned int hashval_t;
....
static hashval_t
t2r_hash (pentry)
     const void * pentry; 
{
  tree entry = (tree) pentry; 
  return ((long long) (((entry)->list.purpose)) & 0777777);
}

and the compiler warnings enclosed here. Apparently, we have to define
MAX_LONG_TYPE_SIZE as a constant. What is the best way to fix it? I
think for mips, we should define MAX_LONG_TYPE_SIZE according to the
target, 32bit or 64bit. I think we should use target_cpu_default to
deal with it. Should I submit a patch?
