LLVM test suite intolerant of '.' in directory names

Extended Description

If you check out LLVM into a directory with '.' characters in the path, the %p variable seems to be mis-expanded when running the LLVM test suite. This causes bogus failures in the test suite.

Specifically, I had a copy of LLVM on my disk in
/Volumes/sandbox/stuart/llvmCore.clang.test2

I believe (at least) these failures were caused by the directory name with period characters:

LLVM :: LLVMC/Alias.td
LLVM :: LLVMC/AppendCmdHook.td
LLVM :: LLVMC/EmptyCompilationGraph.td
LLVM :: LLVMC/EnvParentheses.td
LLVM :: LLVMC/ForwardAs.td
LLVM :: LLVMC/ForwardTransformedValue.td
LLVM :: LLVMC/ForwardValue.td
LLVM :: LLVMC/HookWithArguments.td
LLVM :: LLVMC/HookWithInFile.td
LLVM :: LLVMC/Init.td
LLVM :: LLVMC/LanguageMap.td
LLVM :: LLVMC/MultiValuedOption.td
LLVM :: LLVMC/MultipleCompilationGraphs.td
LLVM :: LLVMC/MultipleOutputLanguages.td
LLVM :: LLVMC/NoActions.td
LLVM :: LLVMC/NoCompilationGraph.td
LLVM :: LLVMC/OneOrMore.td
LLVM :: LLVMC/OptionPreprocessor.td
LLVM :: LLVMC/OutputSuffixHook.td

Obvious workaround: avoid period characters in directory names.
