Xcode: Detect the compiler id and tool location

Configure a hand-generated Xcode project to build the compiler id source
file since we cannot run the compiler command-line tool directly.  Add a
post-build shell script phase to print out the compiler toolset build
setting.  Run xcodebuild to compile the identification binary.  Parse
the full path to the compiler tool from the xcodebuild output.
