[ACTIVITY] Report for week #12

Hello,

[GNU-796] Stabilize GDB testsuite results in the CI:

- Enabled gdb.gdb/unittest.exp in fast_check_gdb job. It should be stable now that tcwg-jade-02's kernel has been upgraded.

- Enabled bisections for check_gdb jobs.

- Implemented Maxim's idea to handle GDB testsuite's tests that can FAIL but are silent when they pass (i.e., the "gdb_test -nopass" statements).

[GNU-767] Support changing SVE vector length in remote debugging

- Back in February I upstreamed a couple of preparation patches and Pedro noticed an unintended change in behaviour that can affect a corner case, so I am working on a fix for that now.
