Unreviewed build fix.

Don't try to copy "Empty.profdata" in production builds where it is not
available. Even though copy-profiling-data.sh may now exit without
creating its output file, XCBuild will still incrementalize correctly
(my prior understanding about missing outputs was wrong).

Don't check for ENABLE_LLVM_PROFILE_GENERATION when defining
CLANG_OPTIMIZATION_PROFILE_FILE. This was breaking the setting's
expansion in the PGO builder, and is unnecesary.

Turn off CLANG_USE_OPTIMIZATION_PROFILE in open source builds.
