I found a few cases where entries in the debug_line for a specific line of code have invalid entries (the address is outside of a code section or no section at all) and also valid entries. When this happens lldb might not set the breakpoint because the first line entry it will find in the line table might be the invalid one and since it's range is "invalid" no location is resolved.

[lldb] [test] Extend watchpoint test to wait for thread to start
TestWatchpointMultipleThreads currently accounts for two scenarios:
setting the watchpoint before a new thread starts (presumably, verifying
that it will be propagated to the new thread) and setting it after
the thread starts (presumably, verifying that a new watchpoint is set
on all threads). However, the latter test currently assumes that
the thread will be reported to the debugger before the breakpoint is
hit. This is not the case on FreeBSD and NetBSD.
On NetBSD, new threads do not inherit debug registers from their parent
threads. Instead, LLDB copies them manually after the new thread is
reported. Since the thread is actually reported after the second
breakpoint location, both tests effectively check the same behavior
(i.e. watchpoint being set before the new thread is reported).
On FreeBSD, new threads inherit debug registers and we seem to hit
an interesting race condition. While the thread is reported after
the breakpoint is hit, the kernel seems to construct it and copy
the debug register before that happens. As a result, setting
the watchpoint at the second breakpoint location modifies the debug
registers of the first thread after they have been copied to the second
thread but before the debugger is aware of it. Therefore,
the watchpoint is not propagated to the second thread and the test
fails.
Extend the test to cover all three possible scenarios: setting
watchpoint before the thread is lanched, after it is launched but before
it is guaranteed to have started and after it has actually started. Add
a second barrier to account for the last case. This should ensure that
the second assumption (i.e. that the watchpoint is set on all currently
known threads) is actually tested on FreeBSD and NetBSD.

Recommit: [llvm-readelf/obj] - Allow dumping of ELF header even if some elements are corrupt.
This is recommit for D90903 with fixes for BB:
1) Used std::move<> when returning Expected<> (http://lab.llvm.org:8011/#/builders/112/builds/913)
2) Fixed the name of temporarily file in the file-headers.test (http://lab.llvm.org:8011/#/builders/36/builds/1269)
(a local old temporarily file was used before)
For creating `ELFObjectFile` instances we have the factory method
`ELFObjectFile<ELFT>::create(MemoryBufferRef Object)`.
The problem of this method is that it scans the section header to locate some sections.
When a file is truncated or has broken fields in the ELF header, this approach does
not allow us to create the `ELFObjectFile` and dump the ELF header.
This is https://bugs.llvm.org/show_bug.cgi?id=40804
This patch suggests a solution - it allows to delay scaning sections in the
`ELFObjectFile<ELFT>::create`. It now allows user code to call an object
initialization (`initContent()`) later. With that it is possible,
for example, for dumpers just to dump the file header and exit.
By default initialization is still performed as before, what helps to keep
the logic of existent callers untouched.
I've experimented with different approaches when worked on this patch.
I think this approach is better than doing initialization of sections (i.e. scan of them)
on demand, because normally users of `ELFObjectFile` API expect to work with a valid object.
In most cases when a section header table can't be read (because of an error), we don't
have to continue to work with object. So we probably don't need to implement a more complex API.

[llvm-readelf/obj] - Allow dumping of ELF header even if some elements are corrupt.
For creating `ELFObjectFile` instances we have the factory method
`ELFObjectFile<ELFT>::create(MemoryBufferRef Object)`.
The problem of this method is that it scans the section header to locate some sections.
When a file is truncated or has broken fields in the ELF header, this approach does
not allow us to create the `ELFObjectFile` and dump the ELF header.
This is https://bugs.llvm.org/show_bug.cgi?id=40804
This patch suggests a solution - it allows to delay scaning sections in the
`ELFObjectFile<ELFT>::create`. It now allows user code to call an object
initialization (`initContent()`) later. With that it is possible,
for example, for dumpers just to dump the file header and exit.
By default initialization is still performed as before, what helps to keep
the logic of existent callers untouched.
I've experimented with different approaches when worked on this patch.
I think this approach is better than doing initialization of sections (i.e. scan of them)
on demand, because normally users of `ELFObjectFile` API expect to work with a valid object.
In most cases when a section header table can't be read (because of an error), we don't
have to continue to work with object. So we probably don't need to implement a more complex API.

Fix debug_abbrev emitter to only assign table id once
While generating yamls for my tests I noticed that the new debug_abbrev format (with multiple table support) was incorrectly assigning id's to the table because it was generating one per abbrev entry in the table. For instance, the first table would get id 4 when 5 abbrev entries existed in the table. By itself this is not a problem but the corresponding debug_info sections were still referencing id 0. This was introduced here: https://reviews.llvm.org/D83116.
Maybe a better fix is to actually correctly calculate the table id when emitting debug info? From a quick glance it seems to me the ID is just being calculated as the distance between the first DWARFAbbreviationDeclarationSet and the one the debug info entry points to, which means it's just its index and not the actual table id that was generated when emitting the debug_abbrev tables. With my fix I guess this is fine but on the diff that introduced this Pavel mentioned that he would like to have some sort of unique id between them but not necessarily +1 increasing, but for that to work we need to actually find the table ID, I guess by going directly to Y.DebugAbbrev but to honest I have no idea how to link the DWARFAbbreviationDeclarationSet and the Y.DebugAbbrev, so I just did this simple fix.
I also realized there's barely any tests for MachO so it might useful to invest on that if the tool is being reworked on.
