James Henderson 7f3135037d [llvm-symbolizer] Flush output on bad input 
One way of using llvm-symbolizer is to interactively within a process
write a line from a parent process to llvm-symbolizer's stdin, and then
read the output, then write the next line, read, etc. This worked as
long as all the lines were good. However, this didn't work prior to this
patch if any of the inputs were bad inputs, because the output is not
flushed after a bad input, meaning the parent process is sat waiting for
output, whilst llvm-symbolizer is sat waiting for input. This patch
flushes the output after every invocation of symbolizeInput when reading
from stdin. It also removes unnecessary flushing when llvm-symbolizer is
not reading addresses from stdin, which should give a slight performance
boost in these situations.
