Issue Description:

description

compiling TSan followed by ASan (or the other way around) in release mode creates linker error, need to wipe the build directory to make it work. (doing the same without the -c release -Xswiftc -enable-testing works fine)

repro

(needs Swift 4.2 pre-releases)

ASan then TSan

git clone https://github.com/apple/swift-nio.git
cd swift-nio
swift build --build-tests --sanitize=address -c release -Xswiftc -enable-testing
# observe how this works
swift build --build-tests --sanitize=thread -c release -Xswiftc -enable-testing

expected

works fine

actual

gives the following errors

Are we not treating --sanitize options as affecting the output files??
