fills in a ToolArgs vector in the AbstractInterpreter if it is set. This
ToolArgs vector is used to pass additional arguments to LLI and/or LLC.
This is intended to address Bug 40.

Also, make -debug-only=toolrunner work for the LLC and CBE
AbstractInterpreters.

to this:

        mov %ECX, %EAX
        sar %ECX, 5

        add %EDX, %ECX
        sar %EAX, 6
        ret

Note that the intel compiler is currently making this:

div:
        movl      4(%esp), %edx                                 #3.5
        movl      %edx, %eax                                    #4.14
        sarl      $5, %eax                                      #4.14
        shrl      $26, %eax                                     #4.14
        addl      %edx, %eax                                    #4.14
        sarl      $6, %eax                                      #4.14
        ret                                                     #4.14

Which has one less register->register copy.  (hint hint alkis :)
