the current stop reason just so it can't go away on us.

The build system is currently miss-identifying GNU/kFreeBSD as FreeBSD.
This kind of simplification is sometimes useful, but in general it's not correct.
As GNU/kFreeBSD is an hybrid system, for kernel-related issues we want to match the
build definitions used for FreeBSD, whereas for userland-related issues we want to
match the definitions used for other systems with Glibc.
The current modification adjusts the build system so that they can be distinguished,
and explicitly adds GNU/kFreeBSD to the build checks in which it belongs.
Fixes bug #16446.
Patch by Robert Millan in the context of Debian.

been suitable for preparing a single IR function
for operation in the target. However, using blocks
and lambdas creates other IR functions that also
need to be processed.
I have audited IRForTarget to make it process
multiple functions. Where IRForTarget would add
new instructions at the beginning of the main
expression function, it now adds them on-demand
in the function where they are needed. This is
enabled by a system of FunctionValueCaches, which
invoke a lambda to create or derive the values as
needed, or report the result of that lambda if it
has already been called for the given function.

Both StopReadThread and the thread being stopped set the thread id to
0 after m_read_thread_enabled was set to false. If the thread being
stopped got there first then StopReadThread called pthread_join on an
invalid thread number. This is not a Good Thing,
Should fix a fairly regular segfault when quitting on Linux.

has more than one function with a body. This
prevents declarations e.g. of blocks from being
passed to the IRInterpreter; they must pass
through to the JIT.

correctly. We have been getting lucky since most
expressions generate only one section (or the first
code section contains all the code), but sometimes
it actually matters.

bother checking if a region is safe to use. In
cases where regions need to be synthesized rather
than properly allocated, the memory reads required
to determine whether the area is used are
- insufficient, because intermediate locations
could be in use, and
- unsafe, because on some platforms reading from
memory can trigger events.
All this only makes a difference on platforms
where memory allocation in the target is impossible.
Behavior on platforms where it is possible should
stay the same.

Also, print the cache hits statistics if the log is in debugging mode vs. LLDB being a debug build - this should make it easier to gather useful metrics on cache success rate for real users

The argument to -w (--category) in type * list is a regular expression
This caused unhappiness with the gnu-libstdc++ category because of the double ++

The semi-unofficial way of returning a status from a Python command was to return a string (e.g. return "no such variable was found") that LLDB would pick as a clue of an error having happened
This checkin changes that:
- SBCommandReturnObject now exports a SetError() call, which can take an SBError or a plain C-string
- script commands now drop any return value and expect the SBCommandReturnObject ("return object") to be filled in appropriately - if you do nothing, a success will be assumed
If your commands were relying on returning a value and having LLDB pick that up as an error, please change your commands to SetError() through the return object or expect changes in behavior

We should probably also return rather than
trying to access the nonexistent return value.
