We've seen some cases on macOS where you go to instruction single
step (over a breakpoint), and single step returns but the instruction
hasn't been executed (and the pc hasn't moved.) The ThreadPlanStepOverBreakpoint
used to handle this case by accident, but the patches to handle two adjacent
breakpoints broke that accident.
This patch fixes the logic of ExplainsStop to explicitly handle the case where
the pc didn't move. It also adds a WillPop that re-enables the breakpoint we
were stepping over. We never want an unexpected path through the plan to
fool us into not doing that.
I have no idea how to make this bug happen. It is very inconsistent when it
occurs IRL. We really need a full MockProcess Plugin before we can start to write
tests for this sort of system hiccup.

PathMappingList was broken for relative and empty paths after normalization changes in FileSpec. There were also no tests for PathMappingList so I added those.
Changes include:
Change PathMappingList::ReverseRemapPath() to take FileSpec objects instead of ConstString. The only client of this was doing work to convert to and from ConstString objects for no reason.
Normalize all paths prefix and replacements that are added to the PathMappingList vector so they match the paths that have been already normalized in the debug info
Unify code in the two forms of PathMappingList::RemapPath() so only one contains the actual functionality. Prior to this, there were two versions of this code.
Use FileSpec::AppendPathComponent() and remove a long standing TODO so paths are correctly appended to each other.
Added tests for absolute, relative and empty paths.

This one will be used to print statistics about lldb sessions
(including, e.g. number of expression evaluation succeeded or
failed). I decided to commit the skeleton first so that we have
a clean reference on how a command should be implemented.
My future commits are going to populate this command and test
it.

Removing the template arguments and most of the mutating methods from
CleanUp makes it easier to understand and reuse.
In its present state, CleanUp would be too cumbersome to adapt to cases
where multiple objects need to be released. Take for example this change
in swift-lldb:
https://github.com/apple/swift-lldb/pull/334/files#diff-6f474df750f75c8ba675f2a8408a5629R219
This change is simple to express with the new CleanUp, but not so simple
with the old version.

from being listed as a part of the desktop or
desktop/desktop_no_xpc Targets - they should not be
a part of any target. Having them listed as a part of
desktop target results in them being added to the
Copy Files build phase for desktop and I'm guessing
they'd end up in the manpage directory or something.

(built with Xcode) from 10.9 to 10.11. It also enables the use of
libcompression in debugserver by default (these API are only present
in macOS 10.11 and newer -- 10.11 was released c. Sep 2015).
I don't know if we have people / bots building lldb on older mac
releases; if this turns out to be a problem I will revert the change.
There are some parts of lldb (e.g. debugserer's ability to report
the OS version #) that only work with 10.10 and this changes the
behavior of lldb (whether the older or newer dyld interfaces are
used) so there is some importance to updating the min required
version.

Summary:
At present, several gtests in the lldb open source codebase are using
#include statements rooted at $(SOURCE_ROOT)/${LLDB_PROJECT_ROOT}.
This patch cleans up this directory/include structure for both CMake and
Xcode build systems.

Summary:
This allows for the stack size to be configured, which isn't
possible with std::thread. Prevents overflowing the stack when
performing complex operations in the task pool on darwin,
where the default pthread stack size is only 512kb.
This also moves TaskPool from Utility to Host.

When introduced, breakpoint names were just tags that you could
apply to breakpoints that would allow you to refer to a breakpoint
when you couldn't capture the ID, or to refer to a collection of
breakpoints.
This change makes the names independent holders of breakpoint options
that you can then apply to breakpoints when you add the name to the
breakpoint. It adds the "breakpoint name configure" command to set
up or reconfigure breakpoint names. There is also full support for
then in the SB API, including a new SBBreakpointName class.
The connection between the name and the breakpoints
sharing the name remains live, so if you reconfigure the name, all the
breakpoint options all change as well. This allows a quick way
to share complex breakpoint behavior among a bunch of breakpoints, and
a convenient way to iterate on the set.
You can also create a name from a breakpoint, allowing a quick way
to copy options from one breakpoint to another.
I also added the ability to make hidden and delete/disable protected
names. When applied to a breakpoint, you will only be able to list,
delete or disable that breakpoint if you refer to it explicitly by ID.
This feature will allow GUI's that need to use breakpoints for their
own purposes to keep their breakpoints from getting accidentally
disabled or deleted.
