Issue Description:

If you move an package's directory between builds, the build fails with this error:

<unknown>:0: error: PCH was compiled with module cache path '/private/tmp/foo/.build/x86_64-apple-macosx10.10/debug/ModuleCache/F6Q938U2LW28', but the path is currently '/private/tmp/bar/.build/x86_64-apple-macosx10.10/debug/ModuleCache/F6Q938U2LW28'
<unknown>:0: error: missing required module 'SwiftShims'
error: terminated(1): /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-build-tool -f /private/tmp/bar/.build/debug.yaml main output:

To reproduce:

cd /tmp
mkdir foo
cd foo
swift package init
swift build
cd ..
mv foo bar
cd bar
swift build

I believe you also can have this same issue when you change Xcode versions between builds.

I think in both of these cases, the files should just be rebuilt automatically, instead of having to `rm -rf .build` and build again.
