Support printing strings which contain invalid utf8 sub-sequences, e.g.
strings like "hello world \xfe", instead of bailing out with "Summary
Unavailable".
I took the opportunity here to delete some hand-rolled utf8 -> utf32
conversion code and replace it with calls into llvm's Support library.

The different tools constructing dotest invocations (lit and
lldb-dotest) already print the command invocation so there's no need to
print it again in the dotest output.
My motivation for removing it is that it doesn't include the Python
interpreter and every time I accidentally copy it, the command fails
with an `ImportError`.

Summary:
Assignment operator `operator=(long long)` currently allocates `sizeof(long)`.
On some platforms it works as they have `sizeof(long) == sizeof(long long)`,
but on others (e.g. Windows) it's not the case.

The Darwin builder is passing some of the make arguments trough the
environment instead of the command line. Update the dsym builder to do
the same as the other variants.
Don't use the environment to pass values to the builder that are present
in the dotest configuration module. A subsequent patch will pass the
remaining values through the configuration instead of the environment.
Summary:
The code changes are very straight-forward -- just handle both DW_AT_GNU
and DW_AT_call versions of all tags and attributes. There is just one
small gotcha: in the GNU version, DW_AT_low_pc was used both for the
"return pc" and the "call pc" values, depending on whether the tag was
describing a tail call, while the official scheme uses different
attributes for the two things.

This patch marks TestCreateDuringInstructionStep.py as flakey for Linux.
This is failing randomly on arm/aarch64. I will monitor buildbot and
skip it if it fails again.
This fixes an unhandled signed integer overflow in AddWithCarry() by
using the llvm::checkedAdd() function. Thats to Vedant Kumar for the

This reverts commit fd0ab3b3eb.
The fix here is incorrect and the actual fault was an incorrect test Makefile.
To give some more background:
The original test for D80798 compiled three source files into either one
executable or one executable + 2 shared libraries, each being one different
test setup. If both the monolithic executable and the shared libraries
where compiled in the same directory, then Make would overwrite the .o files
of one test setup with the other. This caused that while -fPIC was passed
correctly to the test setup with the shared libraries, the compiler invocations
for the monolithic executable would later overwrite these object files (and
as only the test setup with the shared library used -fPIC, it appeared as if
the shared library object files didn't receive the -fPIC flag).
Thanks to Pavel for figuring this out.
Summary:
ClangExpressionSourceCode has different ways to wrap the user expression based on
which context the expression is executed in. For example, if we're in a C++ member
function we put the expression inside a fake member function of a fake class to make the
evaluation possible. Similar things are done for Objective-C instance/static methods.
There is also a default wrapping where we put the expression in a normal function
just to make it possible to execute it.
The way we currently define which kind of wrapping the expression needs is based on
the `wrapping_language` we keep passing to the ClangExpressionSourceCode
instance. We repurposed the language type enum for that variable to distinguish the
cases above with the following mapping:
* language = C_plus_plus -> member function wrapping
* language = ObjC -> instance/static method wrapping (`is_static` distinguished between those two).
* language = C -> normal function wrapping
* all other cases like C_plus_plus11, Haskell etc. make our class a no-op that does mostly nothing.
That mapping is currently not documented and just confusing as the `language`
is unrelated to the expression language (and in the ClangUserExpression we even pretend
that it *is* the actual language, but luckily never used it for anything). Some of the code
in ClangExpressionSourceCode is also obviously thinking that this is the actual language of
the expression as it checks for non-existent cases such as `ObjC_plus_plus` which is
not part of the mapping.
This patch makes a new enum to describe the four cases above (with instance/static Objective-C
methods now being their own case). It also make that enum just a member of
ClangExpressionSourceCode instead of having to pass the same value to the class repeatedly.
This gets also rid of all the switch-case-checks for 'unknown' language such as C_plus_plus11 as this
is no longer necessary.

Summary:
It seems that when we rewrite a few rules to only build a dylib (i.e., when DYLIB_ONLY is set),
the rule for setting the CFLAGS for the dylib's object file compilation will no longer work. From what I can
see this is because in DYLIB_ONLY mode we pretend to compile the main executable so
the DYLIB_OBJECTS scope is actually never used.
This patch makes `-fPIC` unstopped if DYLIB_ONLY is set so that -fPIC actually ends up in the
CFLAGS for the dylib object file compilation.
The test for this is D80798 which only compiles on Linux with this patch.

Commit 0800529fe6 adds a runtime error which triggers when using
SBAddress properties that use the current process/target from a
non-interactive session. TestThreadPlanCommands.py was doing exactly
this and this patch fixes that by use GetLoadAddress instead.
Several SBAddress properties use the lldb.target or lldb.process
convenience variables which are only set under the interactive script
interpreter. Unfortunately, users have been using these properties in
Python script and commands. This patch raises a Python exception to
force users to use GetLoadAddress instead.

We are leaking forked processes on macOS because the cleanup function
was checking the existence of /proc/pid which does not exist on macOS.
I've changed the code to be platform agnostic.
Don't run tests that use undefined behavior sanitizer inside an
address-sanitized LLDB. The tests don't support that
configuration. Incidentally they were skipped on green dragon for a
different reason, so this hasn't come up there before.

One can have multiple simulator runtimes installed, supporting
various generations of OSs. The logic in TestAppleSimulatorOSType
might select a rnutime older than the one targeted by the current
tools, preventing the executable from running. This commit changes
the test to look for the most recent runtime available instead.
Summary:
On Android, this method gets called twice: first when establishing
a host-server connection, then when attaching to a process id.
Each call takes several seconds to finish (especially slower on Windows)
and eliminating the call for the typical case improves latency significantly.

Summary:
This patch adds two new arguments to the MakeInlineTest function. The
main motivation is a follow-up patch I'm preparing, but they seem
generally useful.
The first argument allows the user to specify the "build dictionary".
With this argument one can avoid the need to provide a custom Makefile
if all he needs is to override a couple of make variables. This hooks in
neatly into the existing dictionary support for non-inline tests.
The second argument specifies the name of the test. This could be used
to provide better names to the generated test classes, but it's mainly
useful in conjuction with the first argument: now that we can specify a
custom build dictionary, it may sometimes make sense to run the same
test twice with different build configurations. To achieve that, we need
to give the two tests different names, and this argument achieves that.
The usage of the arguments is demonstrated via TestBasicEntryValues.py.

Jim pointed out that "every time somebody has touched the documentation
on startup files they have stated that we source the application one and
then the global one, even though in actual fact we’ve never done that."
Indeed, when we read the application specific .lldbinit file, the global
one is not read. This patch updates the man page to reflect that.
This adds a new target `check-lldb-reproducers` that replaces the old
`check-lldb-repro`. The latter would only run the shell tests, while
`check-lldb-reproducers` includes the API tests as well. The new target
will be used on GreenDragon.
It's still possible to run just the shell tests with reproducers,
although now that requires crafting the lit invocation yourself. The
parameters haven't changed and are the shame for the API and shell
tests:
--param lldb-run-with-repro=capture
--param lldb-run-with-repro=replay
This patch also updates the reproducer documentation.
This property is explicitly for use only in the interactive editor,
and NOT in commands. It's use worked until we got more careful about
not leaving lldb.target lying around in the script interpreter.
I also added a quick sniff test for the save_crashlog command.

After this patch all remaining tests should pass on macOS when replayed
from a reproducer.
To capture the reproducers:
./bin/llvm-lit ../llvm-project/lldb/test/ --param lldb-run-with-repro=capture
To replay the reproducers:
./bin/llvm-lit ../llvm-project/lldb/test/ --param lldb-run-with-repro=replay
The reproducer don't model timeouts so tests that rely on them end up
with unexpected packets during replay. Skip them until we can handle
this scenario.
