Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes:
- Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file".
- modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly
- Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was.
- modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile()
Cleaned up header includes a bit as well.

Now each command object contains a "ExecutionContext m_exe_ctx;" member variable that gets initialized prior to running the command. The validity of the target objects in m_exe_ctx are checked to ensure that any target/process/thread/frame/reg context that are required are valid prior to executing the command. Each command object also contains a Mutex::Locker m_api_locker which gets used if eFlagTryTargetAPILock is set. This centralizes a lot of checking code that was previously and inconsistently implemented across many commands.

Expanded the flags that can be set for a command object in lldb_private::CommandObject. This list of available flags are:
enum
{
//----------------------------------------------------------------------
// eFlagRequiresTarget
//
// Ensures a valid target is contained in m_exe_ctx prior to executing
// the command. If a target doesn't exist or is invalid, the command
// will fail and CommandObject::GetInvalidTargetDescription() will be
// returned as the error. CommandObject subclasses can override the
// virtual function for GetInvalidTargetDescription() to provide custom
// strings when needed.
//----------------------------------------------------------------------
eFlagRequiresTarget = (1u << 0),
//----------------------------------------------------------------------
// eFlagRequiresProcess
//
// Ensures a valid process is contained in m_exe_ctx prior to executing
// the command. If a process doesn't exist or is invalid, the command
// will fail and CommandObject::GetInvalidProcessDescription() will be
// returned as the error. CommandObject subclasses can override the
// virtual function for GetInvalidProcessDescription() to provide custom
// strings when needed.
//----------------------------------------------------------------------
eFlagRequiresProcess = (1u << 1),
//----------------------------------------------------------------------
// eFlagRequiresThread
//
// Ensures a valid thread is contained in m_exe_ctx prior to executing
// the command. If a thread doesn't exist or is invalid, the command
// will fail and CommandObject::GetInvalidThreadDescription() will be
// returned as the error. CommandObject subclasses can override the
// virtual function for GetInvalidThreadDescription() to provide custom
// strings when needed.
//----------------------------------------------------------------------
eFlagRequiresThread = (1u << 2),
//----------------------------------------------------------------------
// eFlagRequiresFrame
//
// Ensures a valid frame is contained in m_exe_ctx prior to executing
// the command. If a frame doesn't exist or is invalid, the command
// will fail and CommandObject::GetInvalidFrameDescription() will be
// returned as the error. CommandObject subclasses can override the
// virtual function for GetInvalidFrameDescription() to provide custom
// strings when needed.
//----------------------------------------------------------------------
eFlagRequiresFrame = (1u << 3),
//----------------------------------------------------------------------
// eFlagRequiresRegContext
//
// Ensures a valid register context (from the selected frame if there
// is a frame in m_exe_ctx, or from the selected thread from m_exe_ctx)
// is availble from m_exe_ctx prior to executing the command. If a
// target doesn't exist or is invalid, the command will fail and
// CommandObject::GetInvalidRegContextDescription() will be returned as
// the error. CommandObject subclasses can override the virtual function
// for GetInvalidRegContextDescription() to provide custom strings when
// needed.
//----------------------------------------------------------------------
eFlagRequiresRegContext = (1u << 4),
//----------------------------------------------------------------------
// eFlagTryTargetAPILock
//
// Attempts to acquire the target lock if a target is selected in the
// command interpreter. If the command object fails to acquire the API
// lock, the command will fail with an appropriate error message.
//----------------------------------------------------------------------
eFlagTryTargetAPILock = (1u << 5),
//----------------------------------------------------------------------
// eFlagProcessMustBeLaunched
//
// Verifies that there is a launched process in m_exe_ctx, if there
// isn't, the command will fail with an appropriate error message.
//----------------------------------------------------------------------
eFlagProcessMustBeLaunched = (1u << 6),
//----------------------------------------------------------------------
// eFlagProcessMustBePaused
//
// Verifies that there is a paused process in m_exe_ctx, if there
// isn't, the command will fail with an appropriate error message.
//----------------------------------------------------------------------
eFlagProcessMustBePaused = (1u << 7)
};
Now each command object contains a "ExecutionContext m_exe_ctx;" member variable that gets initialized prior to running the command. The validity of the target objects in m_exe_ctx are checked to ensure that any target/process/thread/frame/reg context that are required are valid prior to executing the command. Each command object also contains a Mutex::Locker m_api_locker which gets used if eFlagTryTargetAPILock is set. This centralizes a lot of checking code that was previously and inconsistently implemented across many commands.

Added a new option to the "source list" command that allows us to see where
line tables specify breakpoints can be set in the source. When dumping the
source, the number of breakpoints that can be set on a source line are shown
as a prefix:
(lldb) source list -f test.c -l1 -c222 -b
1 #include <stdio.h>
2 #include <sys/fcntl.h>
3 #include <unistd.h>

entries for them. This helps visualize the data provided in the debug

all inline breakpoint that may result for a given file which can also be very

Added a new option to the "source list" command that allows us to see where
line tables specify breakpoints can be set in the source. When dumping the
source, the number of breakpoints that can be set on a source line are shown
as a prefix:
(lldb) source list -f test.c -l1 -c222 -b
1 #include <stdio.h>
2 #include <sys/fcntl.h>
3 #include <unistd.h>

[1] 8 for (i=0; i<num_secs; ++i)

[1] 21 sleep_loop (20);
22 return 12;

Above we can see there are two breakpoints for line 6 and one breakpoint for
lines 8, 10, 11, 14, 18, 19, 20, 21 and 23. All other lines have no line table
entries for them. This helps visualize the data provided in the debug
information without having to manually dump all line tables. It also includes
all inline breakpoint that may result for a given file which can also be very
handy to see.
