I'm not at home at the moment, so I don't have access to those machines,
but from memory:

LLVM was git master as of sometime around 6-8pm CST last night.  One such
revision would be
commit ffbe432595c78ba28c8a9d200bf92996eed5e5d9
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175718 91177308-0d3


Clang was somewhere between 3bc7b6bef96 and dc84cd5efdd3430efb.

I just retested on another machine with the following versions:
LLVM: git: 0514595b9b20c9d80, svn: 175739
Clang: 7d81281fc39f6d, svn: 175741
Mesa: b63b3012c91 with your clover patch

Result:
Linking C executable ../../../../../bin/cl-custom-run-simple-kernel
/usr/local/lib/libOpenCL.so: undefined reference to
`clang::PPConditionalDirectiveRecord::rangeIntersectsConditionalDirective(clang::SourceRange)
const'
/usr/local/lib/libOpenCL.so: undefined reference to
`clang::PPConditionalDirectiveRecord::findConditionalDirectiveRegionLoc(clang::SourceLocation)
const'
collect2: error: ld returned 1 exit status
make[2]: *** [bin/cl-custom-run-simple-kernel] Error 1
make[1]: ***
[target_api/cl/tests/cl/custom/CMakeFiles/cl-custom-run-simple-kernel.dir/all]
Error 2
make: *** [all] Error 2
