continue_to_breakpoint always continues to the next breakpoint, not to the
one named in parameter. This rendered the tests effectively useless, since
marker2 was never reached.
gdb/testsuite/ChangeLog:
* gdb.reverse/fstatat-reverse.exp: Set breakpoint on marker1 after
reaching marker2.
* gdb.reverse/getresuid-reverse.exp: Likewise.
* gdb.reverse/pipe-reverse.exp: Likewise.
* gdb.reverse/readv-reverse.exp: Likewise.
* gdb.reverse/recvmsg-reverse.exp: Likewise.
* gdb.reverse/time-reverse.exp: Likewise.
* gdb.reverse/waitpid-reverse.exp: Likewise and add KFAILs.
gdb/testsuite/ChangeLog:
* gdb.reverse/fstatat-reverse.c: New test.
