If someone would prefer a clear name for the 'success' error_value we could
come up with one - potentially just a 'named constructor' style
'error_value::success()' to make this expression more self-documenting. If
I see this come up in other cases I'll certainly consider it.

One step along the way to resolving PR11944.

Add a case to test that 'stty -a' displays the same output before and after running the lldb command.

This does make a difference, at least when using RABasic.

Calls clobber the flags, but when using register masks there is no
EFLAGS<imp-def> operand.

I think this was already the intention, but DeadMachineInstructionElim
was accidentally tracking the liveness of reserved registers. Now,
instructions with reserved defs are never deleted.

This prevents the call stack adjustment instructions from getting
deleted when enabling register masks.

which allows values to escape through unknown calls.

Assumes all calls but the malloc family are unknown.

Also, catch a use-after-free when a pointer is passed to a
function after a call to free (previously, you had to explicitly
dereference the pointer value).

optimistic.

TODO: actually implement the pessimistic version of the checker. Ex: it
needs to assume that any function that takes a pointer might free it.

The optimistic version relies on annotations to tell us which functions
can free the pointer.

After discussions with Jim and Greg, modify the 'watchpoint set' command to become a mutiword command
with subcommand 'expression' and 'variable'.  The first subcommand is for supplying an expression to
be evaluated into an address to watch for, while the second is for watching a variable.

'watchpoint set expression' is a raw command, which means that you need to use the "--" option terminator
to end the '-w' or '-x' option processing and to start typing your expression.

Also update several test cases to comply and add a couple of test cases into TestCompletion.py,
in particular, test that 'watchpoint set ex' completes to 'watchpoint set expression ' and that
'watchpoint set var' completes to 'watchpoint set variable '.

For simplicity, treat calls with register masks as basic block
boundaries.  This means we can't copy propagate callee-saved registers
across calls, but I don't think that is a big deal.

Moving toward a uniform style of pass definition to allow easier target configuration.
Globally declare Pass ID.
Globally declare pass initializer.
Use INITIALIZE_PASS consistently.
Add a call to the initializer from CodeGen.cpp.
Remove redundant "createPass" functions and "getPassName" methods.

While cleaning up declarations, cleaned up comments (sorry for large diff).

Creating the isPredicated TSFlag enables the code

instead of using a large switch statement.
