an immediate constant as the shift amount. This is needed for
powerpc Iop_ShlD64 etc. What it basically means that we do not
iterate over the bits in the 2nd operand because there are no
V-bits to set. An immediate constant is always completely defined.

The tester is located in memcheck/tests/vbit-test.
It needs the following support on the valgrind / VEX side:
(1) a new client request VG_USERREQ__VEX_INIT_FOR_IRI
(2) a new "special instruction" on all architectures inserted via
VALGRIND_VEX_INJECT_IR
(3) VEX changes to detect the special insn and insert IR (ir_inject.c)
The README file in vbit-test has some more information.
See also VEX r2490. Fixes bugzilla #300102.
