The ISA 2.07 support adds new Iops as well as support for some existing Iops. None of these Iops have been enabled in the vbit tester. This commit adds the needed support to the files in memcheck/tests/vbit-test. These changes add support for additional immediate operands and additional undefined bit checking functions. There are additional changes to files VEX/priv/ir_inject.c and VEX/pub/libvex.h that are in VEX commit 3202 Bugzilla 354797 was created for this issue. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@15720
