[PATCH] Add -Wno-cast-truncate

Add the ability to turn off checks for casts that truncate constant values
using -Wno-cast-truncate, helpful when attempting to track down a particular
class of warnings only without losing them amongst others.  Checks for
truncating casts default to on, so this does not change the default behavior
of sparse.
