Teach GetXcodeSDK to look in the Xcode that contains LLDB instead of preferring the one chosen with xcode-select. Because we're using xcrun to find matching SDK's you can now get into a situation where LLDB, when run from a non-xcode-selected Xcode will find a matching SDK in the xcode-selected Xcode, which can cause anything from mild performance degradation to really confusing Clang compile errors, if the other Xcode is, for example, older, or missing an SDK.
