Sean Callanan 6961e87847 Added support for dynamic sanity checking in 
expressions.  Values used by the expression are
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

Sean Callanan e71d553cd4 Added a ClangUtilityFunction class that allows the 
debugger to insert self-contained functions for use by
expressions (mainly for error-checking).

In order to support detecting whether a crash occurred
in one of these helpers -- currently our preferred way
of reporting that an error-check failed -- added a bit
of support for getting the extent of a JITted function
in addition to just its base.
