[libc++][NFC] Mark values in gdb pretty print comparison functions as live
to prevent values being optimized out.
It appears when testing LLVM 13 on Power, we run into failures with the
`libcxx/test/libcxx/gdb/gdb_pretty_printer_test.sh.cpp` test case
optimizing
values out.
Despite some the functions in the test already being marked with optnone,
adding the `MarkAsLive()` calls inside of the pretty printer comparison
functions
resolves the issues of the values being optimized out.
This patch aims to address <a href="https://llvm.org/PR51675">https://llvm.org/PR51675</a>.
Differential Revision: <a href="https://reviews.llvm.org/D109204">https://reviews.llvm.org/D109204</a>
(cherry picked from commit 217c6d643124be312f4a99b203118744edb9d54c)
Thanks a lot!</pre>
