 Mark tests for #11643, #11644, #11645 and #9406 expect_broken

 For opt_ways or prof_ways only.

 indexed-types/should_compile/all.T called setTestOpts to not run
 the tests with opt_ways. Since I'm finding regressions for opt_ways, I
 removed it. This only makes a difference when running
 `./validate --slow` or `make slowtest`.

 Update submodule hpc.
