If `HardwareBreakpointTestBase.supports_hw_breakpoints()` returns False,
`SimpleHWBreakpointTest.does_not_support_hw_breakpoints()` returns None,
so the test runs and fails. However, it should be skipped instead.

The test was added in #146602, while `supports_hw_breakpoints()` was
changed in #146609, which was landed earlier despite having a bigger
number.

The test was added in #147252. On a 32-bit target, it fails with error:
```
  File "...\TestDataFormatterLibcxxInvalidString.py", line 23, in test
    self.skip()
    ^^^^^^^^^
AttributeError: 'LibcxxInvalidStringDataFormatterTestCase' object has no attribute 'skip'
```

Make the existing libc++ formatter generic
Add initializer_list summary provider.
Add test for `libstdcpp`

The new test fails on x86 and arm64 public macOS bots:

Reverts llvm/llvm-project#161870

This patch extends ScriptedFrame to work with real (non-scripted)
threads,
enabling frame providers to synthesize frames for native processes.

Previously, ScriptedFrame only worked within
ScriptedProcess/ScriptedThread
contexts. This patch decouples ScriptedFrame from ScriptedThread,
allowing
users to augment or replace stack frames in real debugging sessions for
use
cases like custom calling conventions, reconstructing corrupted frames
from
core files, or adding diagnostic frames.

Key changes:

- ScriptedFrame::Create() now accepts ThreadSP instead of requiring
ScriptedThread, extracting architecture from the target triple rather
than ScriptedProcess.arch

- Added SBTarget::RegisterScriptedFrameProvider() and
ClearScriptedFrameProvider() APIs, with Target storing a
SyntheticFrameProviderDescriptor template for new threads

- Added "target frame-provider register/clear" commands for CLI access

- Thread class gains LoadScriptedFrameProvider(),
ClearScriptedFrameProvider(),
and GetFrameProvider() methods for per-thread frame provider management

- New SyntheticStackFrameList overrides FetchFramesUpTo() to lazily
provide
frames from either the frame provider or the real stack

This enables practical use of the SyntheticFrameProvider infrastructure
in
real debugging workflows.

After #167359 / 95db31e7f69e7008f0c570ed30d54d1e418e10f2.

A fix was attempted in #167423 but was not quite enough.

From what I could understand, in v1 format you have to specify
all the basic blocks. Where before !call_me implied they were all
cold (I think, very shaky understanding here).

For this test we want to see blocks like call_me/foo/call_me.
So adding a line for block 1 fixes the tests.

It could produce more blocks at some point but I think as long
as foo is within two of them, it'll be fine.

After commit fce58897ce82 enabled the locate_module callback for main
executables, the TestLocationsAfterRebuild.py test started failing on
remote platforms. The test was hardcoded to expect breakpoint location
"1.3" to exist after three rebuilds, but the new module loading behavior
changed how breakpoint locations are managed.

This patch fixes the test by:
- Removing the @skipIfRemote decorator to re-enable testing on remote
platforms
- Dynamically querying the actual number of breakpoint locations instead
of assuming a specific count
- Using loc.GetID() to get actual location IDs rather than assuming
sequential IDs (1, 2, 3)
- Iterating through all valid locations and verifying each can be
disabled/enabled

The fix maintains the original test intent (validating that breakpoint
location IDs remain valid after rebuilds) while adapting to the new
module loading behavior where the number and IDs of locations may vary
across platforms.

#160199 broke buildbots `lldb-remote-linux-ubuntu` and
`lldb-remote-linux-win`.
This patch must make these buildbots green for now.
