Subject: [PATCH] lit.cfg: Remove substitutions for clang/llvm tools

We were missing some subsitutions, for example 'not with no pipe, so
there was a mismatch where some tests would run tools using the full
path and others would search PATH for the tool.

The new beahavior is that the lit tests will always search PATH for the
tool.  This should not change the current functionality, because the
smae paths that were being used in substitutions are being added to
PATH.
