BITS_PER_WORD is not right. That is what prompted me to make the
change.  There are a few things about the MIPS ABI:

1. We do follow the ABI part.
2. We care much less about the API part. That is in the section 6 where
wchar_t is defined.
3. On mips, sizeof (int) == sizeof (long int).

But BITS_PER_WORD can be 32 or 64, depending on TARGET_LONG64. As for
WCHAR_TYPE, it should be `int' regardless of TARGET_LONG64. For most of
the 64bit Linux targets, sizeof (int) should be 32bit. That means
WCHAR_TYPE_SIZE should be 32 for mips.
