Improve the error message when a PCH dependency is modified Show the top-level pch file as the culprit, rather than the immediate dependency when a pch file imports a pcm from a module. To clarify the relationship, the pch import stack is printed as notes. The old behaviour was misleading when a pch imported a pcm (from a module), since removing the pcm would not fix the problem, whereas rebuilding the pch would. llvm-svn: 199446 2014-01-17 08:19:09 +08:00			`module test {`
