  tests: remove mostly-redundant tests on silent rules
  
  We used to have several couples of tests named like 'silent-foo-gcc.sh'
  and 'silent-foo-generic.sh'.  Differently from what the names suggest,
  the first test in such a couple (that is, "silent-foo-gcc.sh") was not
  meant to check specific GCC-related features, but rather to check how
  the silent rules behave in combination with automatic dependency tracking
  when the 'gcc' depmode (that targets GCC versions before the 3.x and 4.x
  release series) is forced.
  
  Such depmode forcing was done exclusively to cover the code paths in
  'lib/am/depend2.am' that actually invoke the 'depcomp' script, rather
  than using the inlined, GCC-specific compiler invocation (the so-called
  "fastdep" mode), which is the default with modern GCC or with other
  modern compilers that can emulate the GCC command-line interface (e.g.,
  clang 3.0).
  
  But whenever we run the silent-*-generic.sh" tests with other supported
  compilers which have an associated depmode different from 'gcc3', these
  same "non-fastdep" code paths are covered, since in those tests we run
  ./configure with the '--enable-dependency-tracking' option, which causes
  slower depmodes not to be rejected.  Examples of such compilers are the
  Sun C and C++ compilers (at least since version 5.9, a.k.a. Sun Studio
  12.1), and the Tiny C Compiler (from version 0.9.26); and I run the
  Automake testsuite quite regularly with those compilers.
  
  So, the "silent-*-gcc.sh" test cases don't offer any real coverage
  enhancements, while still using testsuite runtime and causing some
  (admittedly minor, but still annoying) synchronization headaches with
  the sister tests "silent-foo-general.sh" tests.  So let's just remove
  these "silent-*-gcc.sh" tests.
