Remove unnecessary case in fits_in_uint_helper

The width == 1 case in this switch statement was left over from when booleans
were stored as uint(1)s, which is not relevant as of my boolean immediate size
work on June 17th.  I think I missed this case because it didn't involve an
immediate directly.
Fix Coverity issue 1212320

Coverity was correctly complaining about the primitive PRIM_FIELD_NUM_TO_NAME.
If the field number specified exceeded the number of fields in the record or
class, then the compiler would not modify the variable name before using it,
causing a dereference of null.  I have added a test for this case and an error
message to the user should this occur in their code.
