[analyzer] Add a checker for loss of sign or precision in integral casts.
This new checker tries to find execution paths on which implicit integral casts
cause definite loss of information: a certainly-negative integer is converted
to an unsigned integer, or an integer is definitely truncated to fit into
a smaller type.
Being implicit, such casts are likely to produce unexpected results.
Patch by Daniel Marjamäki!
