Roll valgrind-variant r144 for Mac OS 10.6
This is still Valgrind r13132 VEX r2564, but with several patches (see https://code.google.com/p/valgrind-variant/source/list
for the list of patches from r139 to r144)
The particular reason for this roll is r144, which brings back the <load_obj> tags in the XML output mode on OS X.
