David Spickett 0a36c72dee [libcxx][pretty printers] Check GDB Python scripting support
I found this after upgrading from Ubuntu bionic (gdb 8.1.1) to
Focal (gdb 9.2). (where this test fails, but that's for a
different patch)

9.2 allows you to set breakpoint commands from
Python, which was added in 8.3.
(bintutils a913fffbdee21fdd50e8de0596358be425775678
"Allow breakpoint commands to be set from Python")

The reason this test never failed before was because it did so
silently. "source <python file>" doesn't fail even if that script
raises an Exception.

To fix this extend the gdb lit feature to check that:
* gdb exists
* has Python support
* allows you to set breakpoint commands

Amy Kwan 217c6d6431 [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 https://llvm.org/PR51675.

Sterling Augustine 55b7061116 Tolerate missing debug info in the shared_ptr pretty printer.
Certain fields of shared ptr have virtual functions and therefore
have their debug info homed in libc++. But if libc++ wasn't built
with debug info, the pretty printer would fail.

This patch makes the pretty printer tolerate such conditions and
updates the test harness.

This patch significantly reworks a previous attempt.

Petr Hosek 9ac988f6a8 [libcxx] Make the GDB pretty printer test less strict
This is a workaround for PR48937. GDB can sometimes print additional
warnings which currently fails the test. Use re.search instead of
re.match to ignore this additional output.

Sterling Augustine a34b8b879e Various minor fixes for python 3
Switch StdTuple printer from python 2-style "next" to python 3.

Nested iteration changed enough to make the original bitset iteration
code a bit trickier than it needs to be, so unnest.

The end node of a map iterator is sometimes hard to detect in isolation,
don't fail in that case.

Louis Dionne 7ad8e19958 [libc++] Move the GDB pretty printer tests to the DSL
Also, enable them whenever we detect that gdb is available. Previously,
these tests would basically never run because they relied on a CMake
configuration option that defaulted to OFF.
