When createInstrumentedIndirectCall() was invoked for tail calls, we
attached annotation instruction twice to the new call instruction.
First in createDirectCall(), and then again while copying over the
metadata operands.
As a result, the annotations were not properly stripped for such calls
before the call to freeAnnotations() in LowerAnnotations pass. That lead
to use-after-free while restoring the offsets with setOffset() call.
