  Changed paths:
    M clang/include/clang/Basic/DiagnosticFrontendKinds.td
    M clang/lib/Basic/TargetInfo.cpp
    A clang/test/Frontend/invalid-target-feature.c

  Log Message:
  -----------
  [Clang] Improve diagnostics about the invalid target feature.

Clang with debug builds will crash when run with empty target feature input.
And the warning message is a little bit confusing. This patch adds an empty
check and a new diagnostic to illustrate where goes wrong.
