Jonas Devlieghere 0274c797c6 [lldb/Utils] Serialize exit code in lldb-repro.py
After 61d5b0e663 more shell test are expected to exit with a non-zero
status code. Because the exit status is computed in the driver and not
behind the SB API layer, reproducers don't know about it and always
return 0 unless replay failed.

This discrepancy means that these tests don't work with lldb-repro.py
and skipping them for this reason would be a pity. To solve this
problem, the script now serializes the exit code during capture and
returns that during replay.

These is an assert that ensures that replay exits with a zero exit
status to prevent replay failures from being silently ignored.

Walter Erquinigo da0e91fee6 [intel-pt] Improve the way the test determines whether to run
Summary:
@labath raised a concern on the way I was skipping this test. I think that was
fair and I found a better way.
Now I'm skipping if the CMAKE flag LLDB_BUILD_INTEL_PT is false.
I added an enabled_plugins entry in the dotest configuration, which gets
set by lit or lldb-dotest. The only available plugin right now is
'intel-pt', but I imagine it will be useful in the future for other
kinds of plugins that get determined at configuration time. I didn't
want to add a new argument option --enable-intel-pt or something or the
sort, as it wouldn't be useful for other cases.

Jonas Devlieghere 09c8845adf [lldb]/Tablegen] Use ElementType instead of DefaultValueUnsinged
The fourth field in the property struct is the default unsigned or enum
value for all types, except for Array and Dictionary types. For those,
it is the element type. During the tablegen conversion, this was
incorrectly translated to DefaultValueUnsigned with a value
corresponding to the OptionValue: enum type. So for
OptionValue::eTypeString this became DefaultUnsignedValue<16>. This
patch extends the tablegen backend to understand ElementType to express
this as ElementType<"String">.

Stella Stamenova d53c8c6af5 [lldb/tests] Correctly configure the lldb dotest arguments
Summary:
When the generator used for CMake is a multi-configuration generator (such as VS), the arguments passed to dotest are not currently configured correctly. There are a couple of issues:
1) The per-configuration files are all generated for the same configuration since the for loop overwrites the properties
2) Not all of the parameters are configured in the lit cfg, so they end up with %(build_mode)s as configuration and they point to non-existent paths

During the first run, it captures a reproducer for every lldb invocation
and saves it to a well-know location derived from the arguments and
current working directory. During the second run, the test suite is run
again but this time every invocation of lldb replays the previously
recorded session.

Jonas Devlieghere ff5982aa91 [test] Fix various module cache bugs and inconsistencies
Currently, lit tests don't set neither the module cache for building
inferiors nor the module cache used by lldb when running tests.
Furthermore, we have several places where we rely on the path to the
module cache being always the same, rather than passing the correct
value around. This makes it hard to specify a different module cache
path when debugging a a test.

This patch reworks how we determine and pass around the module cache
paths and fixes the omission on the lit side. It also adds a sanity
check to the lit and dotest suites.

This patch removes the -q (quiet) flag and changing the default

contradictory, as illustrated by the difference between the argument

result of individual tests. My proposal is to guard the extra output
behind the verbose flag and always print the individual test results.

Unfortunately we cannot do the same for enums, as there's this magic
ePropertyExperimental, which needs to come at the end to be interpreted
correctly. Hopefully we can get rid of this in the future and do the
same for the property enums.

Jonas Devlieghere 971f9ca612 Let tablegen generate property definitions
Property definitions are currently defined in a PropertyDefinition array
and have a corresponding enum to index in this array. Unfortunately this
is quite error prone. Indeed, just today we found an incorrect merge
where a discrepancy between the order of the enum values and their
definition caused the test suite to fail spectacularly.

Tablegen can streamline the process of generating the property
definition table while at the same time guaranteeing that the enums stay
in sync. That's exactly what this patch does. It adds a new tablegen
file for the properties, building on top of the infrastructure that
Raphael added recently for the command options. It also introduces two
new tablegen backends: one for the property definitions and one for
their corresponding enums.

It might be worth mentioning that I generated most of the tablegen
definitions from the existing property definitions, by adding a dump
method to the struct. This seems both more efficient and less error
prone that copying everything over by hand. Only Enum properties needed
manual fixup for the EnumValues and DefaultEnumValue fields.

Raphael Isemann 6f4fb4e7ad [lldb] Let table gen create command option initializers.
Summary:
We currently have man large arrays containing initializers for our command options.
These tables are tricky maintain as we don't have any good place to check them for consistency and
it's also hard to read (`nullptr, {}, 0` is not very descriptive).

This patch fixes this by letting table gen generate those tables. This way we can have a more readable
syntax for this (especially for all the default arguments) and we can let TableCheck check them
for consistency (e.g. an option with an optional argument can't have `eArgTypeNone`, naming of flags', etc.).

Also refactoring the related data structures can now be done without changing the hundred of option initializers.

For example, this line:
```
{LLDB_OPT_SET_ALL, false, "hide-aliases",         'a', OptionParser::eNoArgument, nullptr, {}, 0, eArgTypeNone, "Hide aliases in the command list."},
```
becomes this:
```
  def hide_aliases : Option<"hide-aliases", "a">, Desc<"Hide aliases in the command list.">;
```

For now I just moved a few initializers to the new format to demonstrate the change. I'll slowly migrate the other
option initializers tables  in separate patches.
