Part of integrate.c appears to assume this, but it's not documented:
If code is an RTX code, and GET_RTX_CLASS (code) is '1', 'b', or '3',
is GET_RTX_FORMAT (code) guaranteed to begin with 'e'?
If x is a valid RTX, and GET_RTX_FORMAT (GET_CODE (x)) is a string
beginning with 'e', is GET_MODE (XEXP (x, 0)) guaranteed to be other
than VOIDmode?
