[PATCH] D35789: [XRay][compiler-rt] Do not print the warning when the binary is not XRay instrumented.

[Dean Michael Berris via Phabricator via llvm-commits]

dberris created this revision.

Currently when the XRay runtime is linked into a binary that doesn't
have the instrumentation map, we print a warning unconditionally. This
change attempts to make this behaviour more quiet.
