[PATCH] Change ClangTool::run output processing file to debug output

[Ariel Bernal]

Hi revane,

Changed processing output to debug output
    
By default ClangTool::run writes the processing file name to standard output. Changed this to be a DEBUG output, enabled by -debug option.
Also changed the error while processing file message to standard error.
    
pch.cpp was change to account for the empty output resulting from executing clang-check.
