    IMPALA-8250: Remove unused THROW_IF_ERROR_WITH_LOGGING, THROW_IF_EXC, and 
RETURN_IF_EXC.
    
    These macros have no references, so removing them. Found while
    investigating JNI warnings in IMPALA-8250.
    
    The following one-liner does a hap-hazard job of finding similar issues.
    There are relatively few left, and none of them seemed problematic.
    
      (for x in $(git grep '#define' be/src | grep -v be/src/kudu | grep -v 
be/src/gutil | grep -v be/src/thirdparty | grep -v be/src/transport/config.h | 
awk '{ print $2 }' | sed -e 's,(.*,,' | sort | uniq); do echo -n "$x "; git 
grep -e $x | wc -l; done) | awk '$2 == 1 { print }'
    
    Note that some of the macros were broken, because they
    called other JNI functions before calling ExceptionClear().
