    M bolt/include/bolt/Passes/ValidateInternalCalls.h
    M bolt/lib/Passes/ValidateInternalCalls.cpp

  Log Message:
  [BOLT] Process each block only once in fixCFGForPIC

Rather than iterating over the whole function from the start until no
internal calls are found, process each block only once and continue
processing after splitting. This version of the function also does not
seemingly invalidate iterators from within the loop.
