Fix the builds with LLVM_TOOL_LLVM_DRIVER_BUILD enabled.
LLVM_ENABLE_EXPORTED_SYMBOLS_IN_EXECUTABLES is not completely
compatible with export_executable_symbols as the later will be ignored
if the previous is set to NO.
Fix the issue by passing if symbols need to be exported to
llvm_add_exectuable so the link flag can be determined directly
without calling export_executable_symbols_* later.

This reapplies 85c649bc02a, which was reverted in 35767e43d62 due to failures
with some example programs. The fix was to add export_executable_symbols to the
example programs.
