The /proc/<pid>/status parsing is missing a few cases:
- Idle
- Parked
- Dead
If we encounter an unknown proc state, this leads to an msan warning. In reality, we only check that the state != Zombie, so it doesn't really matter that we handle all cases, but handle them anyway (current list: [1]). Also explicitly set it to unknown if we encounter an unknown state. There will still be an msan warning if the proc entry has no `State:` line, but that should not happen.
Use a StringSwitch to make the handling of proc states a little more compact.

This patch adds the ability to use a custom interpreter with the
`platform shell` command. If the user set the `-s|--shell` option
with the path to a binary, lldb passes it down to the platform's
`RunShellProcess` method and set it as the shell to use in
`ProcessLaunchInfo to run commands.
Note that not all the Platforms support running shell commands with
custom interpreters (i.e. RemoteGDBServer is only expected to use the
default shell).
This patch also makes some refactoring and cleanups, like swapping
CString for StringRef when possible and updating `SBPlatformShellCommand`
with new methods and a new constructor.

Currently it is hard to avoid having LLVM link to the system install of
ncurses, since it uses check_library_exists to find e.g. libtinfo and
not find_library or find_package.
With this change the ncurses lib is found with find_library, which also
considers CMAKE_PREFIX_PATH. This solves an issue for the spack package
manager, where we want to use the zlib installed by spack, and spack
provides the CMAKE_PREFIX_PATH for it.

TestCompletion is randomly failing on some bots. The error message however states
that the computed completions actually do contain the expected pid we're
looking for, so there shouldn't be any test failure.
The reason for that turns out to be that complete_from_to is actually used
for testing two different features. It can be used for testing what the
common prefix for the list of completions is and *also* for checking all the
possible completions that are returned for a command. Which one of the two
things should be checked can't be defined by a parameter to the function, but
is instead guessed by the test method instead based on the results that were
returned. If there is a common prefix in all completions, then that prefix
is searched and otherwise all completions are searched.
For TestCompletion's pid test this behaviour leads to the strange test failures.
If all the pid's that our test LLDB can see have a common prefix (e.g., it
can only see pids [123, 122, 10004, 10000] -> common prefix '1'), then
complete_from_to check that the common prefix contains our pid, which is
always fails ('1' doesn't contain '123' or any other valid pid). If there
isn't a common prefix (e.g., pids are [123, 122, 10004, 777]) then
complete_from_to will check the list of completions instead which works correctly.
This patch is fixing this by adding a simple check method that doesn't
have this behaviour and is simply searching the returned list of completions.
This should get the bots green while I'm working on a proper fix that fixes
complete_from_to.
Right now all tsan tests are crashing on Linux. The tests were already marked as
expected failures, but since commit 20ce8affce added an assert that every
StopInfo needs a non-empty stop description the tests actually started crash
(which is even with an expectedFailure a failed test).
The reason for that is that we never had any stop description when hitting tsan
errors on Linux. Before the assert that just made the test fail, but now the
empty description is hitting the assert. This patch just adds a generic stop
description mentioning tsan to prevent that we hit that assert on platforms
where we don't support extracting the tsan report.

LIT uses a model where the test suite is configurable trough a
lit.site.cfg file. Most of the time we use the lit.site.cfg with values

Nothing prevents you from running the test suite with a different
configuration, either by overriding some of these values from the
command line, or by passing a different lit.site.cfg.
The latter is currently tedious. Many configuration values are optional
but they still need to be set because lit.cfg.py is accessing them
directly. This patch changes the code to use getattr to return the
attribute if it exists. This makes it possible to specify a minimal
lit.site.cfg with only the mandatory/desired configuration values.

This fixes several issues in handling of DW_AT_const_value attributes:
- the first is that the size of the data given by data forms does not
need to match the size of the underlying variable. We already had the
case to handle this for DW_FORM_(us)data -- this extends the handling
to other data forms. The main reason this was not picked up is because
clang uses leb forms in these cases while gcc prefers the fixed-size
ones.
- The handling of DW_AT_strp form was completely broken -- we would end
up using the pointer value as the result. I've reorganized this code
so that it handles all string forms uniformly.
- In case of a completely bogus form we would crash due to
strlen(nullptr).

Breakpad will always have a UUID for binaries when it creates minidump files. If an ELF files has a GNU build ID, it will use that.

LLDB will use the GNU build ID first as the main UUID for a binary and fallback onto a 8 byte CRC if a binary doesn't have one.

point semantics (which would be needed for fully supporting
architectures with more interesting float types such as PPC).

This is very similar to D85968, only more elusive to since we were not
adding the typedef type to the relevant DeclContext until D86140, which
meant that the DeclContext was populated (and the relevant assertion
hit) only after importing the type into the expression ast in a
particular way.
I haven't checked whether this situation can be hit in the gmodules
case, but my money is on "yes".

I move the triple (de)composition logic into the builder in e5d08fcbac
but this test is relying on Make to construct the set the ARCH,
ARCH_CFLAGS and SDKROOT based on the given TRIPLE. This patch updates
the test to pass these variables directly.

This patch adds the infrastructure to have language specific REPL init
files. It's the foundation work to a following patch that will introduce
Swift REPL init file.
When lldb is launched with the `--repl` option, it will look for a REPL
init file in the home directory and source it. This overrides the
default `~/.lldbinit`, which content might make the REPL behave
unexpectedly. If the REPL init file doesn't exists, lldb will fall back
to the default init file.

Print which load command we were looking for when the sanity check
fails:
AssertionError: 0 != 1 : wrong number of load commands for
LC_VERSION_MIN_MACOSX
Instead of a new method for each variable any subclass might want to
set, have a method getExtraMakeArgs that each subclass can use to return
whatever extra Make arguments it wants.
As per Pavel's suggestion in D85539.
Rather than have different modules for different platforms, use
inheritance so we can have a Builer base class and optional child
classes that override platform specific methods.

TypeSystemClang::CreateTypedef was creating a typedef in the right
DeclContext, but it was not actually adding it as a child of the
context. The resulting inconsistent state meant that we would be unable
to reference the typedef from an expression directly, but we could use
them if they end up being pulled in by some previous subexpression
(because the ASTImporter will set up the correct links in the expression
ast).
This patch adds the typedef to the decl context it is created in.
