fdc6aea3fd [lldb] Check Decl kind when completing -flimit-debug-info types
The search for the complete class definition can also produce entries
which are not of the expected type. This can happen for instance when
there is a function with the same name as the class we're looking up
(which means that the class needs to be disambiguated with the
struct/class tag in most contexts).

Previously we were just picking the first Decl that the lookup returned,
which later caused crashes or assertion failures if it was not of the
correct type. This patch changes that to search for an entry of the
correct type.

dd0fdf8030 [lldb] Add support for checking children in expect_expr
expect_expr currently can't verify the children of the result SBValue.

This patch adds the ability to check them. The idea is to have a CheckValue
class where one can specify what attributes of a SBValue should be checked.
Beside the properties we already check for (summary, type, etc.) this also
has a list of children which is again just a list of CheckValue object (which
can also have children of their own).

The main motivation is to make checking the children no longer based
on error-prone substring checks that allow tests to pass just because
for example the error message contains the expected substrings by accident.

I also expect that we can just have a variant of `expect_expr` for LLDB's
expression paths (aka 'frame var') feature.

1956cf1042 [lldb/DWARF] Don't treat class declarations with children as definitions
Summary:
This effectively reverts r188124, which added code to handle
(DW_AT_)declarations of structures with some kinds of children as
definitions. The commit message claims this is a workaround for some
kind of debug info produced by gcc. However, it does not go into
specifics, so it's hard to reproduce or verify that this is indeed still a
problem.

Having this code is definitely a problem though, because it mistakenly
declares incomplete dwarf declarations to be complete. Both clang (with
-flimit-debug-info) and gcc (by default) generate DW_AT_declarations of
structs with children. This happens when full debug info for a class is
not emitted in a given compile unit (e.g. because of vtable homing), but
the class has inline methods which are used in the given compile unit.
In that case, the compilers emit a DW_AT_declaration of a class, but
add a DW_TAG_subprogram child to it to describe the inlined instance of
the method.

Even though the class tag has some children, it definitely does not
contain enough information to construct a full class definition (most
notably, it lacks any members). Keeping the class as incomplete allows
us to search for a real definition in other modules, helping the
-flimit-debug-info flow. And in case the definition is not found we can
display a error message saying that, instead of just showing an empty
struct.

Summary:
This patch adds support for AArch64 SVE register infos description and
core file register access.

AArch64 SVE is a an optional extension of Arm v8.3-a architecture. It
has introduced 32 new vector registers Z, 16 predicate P registers and FFR
predicate register. These registers have fixed names but can dynamically
be configured to different size based on underlying OS configuration.

This patch adds register info struct that describes SVE register infos and
also provides RegisterContextPOSIXCore_arm64 routines to access SVE registers.

This patch also introduces a mechanism to configure SVE register sizes and
offsets at startup before exchanging register information across gdb-remote.

TestLinuxCore.py has been updated to include testing of SVE core files.

16926115ed [lldb] Only set the executable module for a target once
Summary:

When we try to find the executable module for our target we don't check
if we already have an executable module set. This causes that when debugging
a program that dlopens another executable, LLDB will take that other executable
as the new executable of the target (which causes that future launches of the
target will launch the dlopen'd executable instead of the original executable).

This just adds a check that we only set the executable when we haven't already
found one.

001c78de35 [lldb][formatters] Add support for printing NSConstantDate and fix distantPast value
Summary:

Certain `NSDate` constructors return a special `NSConstantDate` class which
currently ends up being unformatted as it's not in the list of supported classes
for the NSDate formatter. This patch adds that class to the supported class list
so LLDB produces a summary for it.

One of these special constructors is `[NSDate distantPast]` which returns the
date for `0001-01-01 00:00:00 UTC`. LLDB has a special case for formatting this
date but for some reason we did hardcode the wrong summary string in that
special case. Maybe the summary string was correct back when the code was
written but it isn't correct anymore (`distantPast` isn't actually defined to be
a special date but just some 'a guaranteed temporal boundary.' so maybe someone
changed the value in the last 10 years).

If someone else is wondering why we even have this special case for
`distantPast` but not for the future. The reason seems to be that our date
formatting for really old dates is off by 24 hours. So for example, adding one
second to `distantPast` will cause LLDB to print `0000-12-30 00:00:01 UTC`
(which is 24 hours behind the expected result). So to make our code appear to be
correct it seems we just hardcoded the most common NSDate result from that time
span. I'll replace that logic with a generic solution in a probably more
invasive follow up patch.

I also took the freedom to replace the magic value `-63114076800` with some
constant + documentation. I heard there are some people that don't know from the
top of their head that there are 63114076800 seconds between 1. Jan 0001 and 1.
January 2001 in whatever calendar system NSDate is using.
