[PATCH] D46819: [llvm-objcopy] Add --keep-symbol (-K) option

btw, i've looked at the code one more time, it seems to me it's not completely correct, the situation is a bit more subtle.
For example,

main.c:
int xx= 1;
int yy() { return 239; }

gcc -g -c main.c -o main.o
cp  main.o _main.o

objcopy --keep-symbol=xx --strip-all main.o -o main2.o
llvm-objcopy --keep-symbol=xx --strip-all _main.o -o _main2.o

llvm-objcopy will entirely wipe out the symbols table, the logic appears to be wrong 
(bintuils objcopy does the right thing at the same time)
