interface flag (runStarted) indicating whether the lldb "run"/"process launch"
command has been issued.  It was erroneously cleared.

Modified the test cases to take advantage of the refactoring.

function statics, file globals and static variables) that a frame contains. 
The StackFrame objects can give out ValueObjects instances for
each variable which allows us to track when a variable changes and doesn't
depend on variable names when getting value objects.

StackFrame::GetVariableList now takes a boolean to indicate if we want to
get the frame compile unit globals and static variables.

The value objects in the stack frames can now correctly track when they have
been modified. There are a few more tweaks needed to complete this work. The
biggest issue is when stepping creates partial stacks (just frame zero usually)
and causes previous stack frames not to match up with the current stack frames
because the previous frames only has frame zero. We don't really want to 
require that all previous frames be complete since stepping often must check
stack frames to complete their jobs. I will fix this issue tomorrow.

checked by validation functions which cause the
program to crash if the values are unsafe.

Major changes:

- Added IRDynamicChecks.[ch], which contains the
  core code related to this feature

- Modified CommandObjectExpression to install the
  validator functions into the target process.

- Added an accessor to Process that gets/sets the
  helper functions

persistent variables were staying around too long.
This caused the following problem:

- A persistent result variable is created for the
  result of an expression.  The pointer to the
  corresponding Decl is stored in the variable.

- The persistent variable is looked up during
  struct generation (correctly) using its Decl.

- Another expression defines a new result variable
  which happens to have a Decl in the same place
  as the original result variable.

- The persistent variable is looked up during
  struct generation using its Decl, but the old
  result variable appears first in the list and
  has the same Decl pointer.

The fix is to destroy parser-specific data when
it is no longer valid.

Also improved some logging as I diagnosed the
bug.

Modified hello_world/TestHelloWorld.py to have two test cases:

o test_with_dsym_and_run_command
o test_with_dwarf_and_process_launch_api

with the dsym case conditioned on sys.platform.startswith("darwin") being true.
The two cases utilize the system() method to invoke "make clean; make MAKE_DYSM=YES/NO"
to prepare for the appropriate debugging format before running the test logic.
