[testsuite] Fix plugin testsuite, remove uses of TODO_dump_func (PR testsuite/52948)

[Rainer Orth <ro at CeBiTec dot Uni-Bielefeld dot DE>]

As reported in PR testsuite/52948, several plugin testcases were failing
since the removal of TODO_dump_func:

UNRESOLVED: selfassign.c compilation, -I. -I/vol/gcc/src/hg/trunk/local/gcc/testsuite -I/vol/gcc/src/hg/trunk/local/gcc/testsuite/../../gcc -I/var/gcc/regression/trunk/11-gcc/build/gcc/testsuite/g++/../../../gcc  -I/vol/gcc/src/hg/trunk/local/gcc/testsuite/../../include -I/vol/gcc/src/hg/trunk/local/gcc/testsuite/../../libcpp/include  -I/vol/gcc/include -I/vol/gcc/include -I/vol/gcc/include  -I/var/gcc/regression/trunk/11-gcc/build/gcc/testsuite/g++/../../../intl -O -DIN_GCC -fPIC -shared

I have no idea why this has been missed when testing the removal patch,
because the failures are very prominent in mail-report.log (maybe
because the incorrectly show up as UNRESOLVED instead of FAIL).

This patch fixes this by removing the uses of TODO_dump_func from the
affected plugins.

At the same time, I'm finally fixing some issues with the plugin tests
that have annoyed me for quite some time:

* The tests should log the full (relative) path to the testcase, not
  only the basenames.

* Using unresolved to report failures to compile the plugins is wrong:
  this should be fail instead, and the pass case needs to be logged as
  well.

* There's no point in logging the options used to compile the plugin:
  they are completely internal to plugin-support.exp and not in any way
  influenced by the testsuite drivers.

There's one issue I didn't fix due to the large number of (bad)
precedents in the testsuite:

* If a plugin fails to compile, the compilations using it should become
  unresolved instead of just returning early.

Bootstrapped without regressions on i386-pc-solaris2.11, installed on
mainline.
