Test the overhead of dereferencing strings

Run as 'stap -gt deref-string.stp', and add '-DTEST_DIRECT' for direct memory
access.  My results on 2.6.26-rc3 x86_64:

OLD:
direct: 1725min/2072avg/10283max
deref: 1778min/2085avg/10950max

NEW:
direct: 1650min/2012avg/10613max
deref: 2152min/2476avg/12563max
