Adapt to debugIntrinsics option in crucible

[RyanGlScott]

GaloisInc/crucible#782 adds a new debugIntrinsics option, which controls whether llvm.dbg statements should be translated or not, to various functions in crucible-llvm:Lang.Crucible.LLVM.Translation, which will affect SAW. While tools like Crux can safely set debugIntrinsics to False, as they do not make use of llvm.dbg intrinsics, SAW does make use of these intrinsics (see #1385). As a result, we'll need to be a bit careful when updating SAW to use GaloisInc/crucible#782. We'll likely want to add a SAW option for configuring the value of debugIntrinsics, since there are programs (such as the one identified in GaloisInc/crucible#778) that currently will not work in Crucible with the debug intrinsics present.

GaloisInc/crucible#782 has landed, but I'll wait until after #1403 (which updates the crucible submodule up until the point of GaloisInc/crucible#782's commits) lands before making the necessary changes SAW-side.
