Nico Weber 28db4445e2 libcxx: Rename .hpp files in libcxx/test/support to .h
LLVM uses .h as its extension for header files.

Files renamed using:

    for f in libcxx/test/support/*.hpp; do git mv $f ${f%.hpp}.h; done

References to the files updated using:

    for f in $(git diff master | grep 'rename from' | cut -f 3 -d ' '); do
        a=$(basename $f);
        echo $a;
        rg -l $a libcxx | xargs sed -i '' "s/$a/${a%.hpp}.h/";
    done

HPP include guards updated manually using:

    for f in $(git diff master | grep 'rename from' | cut -f 3 -d ' '); do
      echo ${f%.hpp}.h ;
    done | xargs mvim
