Thread the Lithium instruction down to DeoptimizeIf and friends.

Thread the Lithium instruction down to DeoptimizeIf and friends.

This is a purely mechanical refactoring and a first step towards being
able to report more helpful deoptimization reasons. With this
refactoring, we know at least the mnemonic of the instruction causing
the deopt, although this is not used yet. Future steps will be using
the mnemonic, passing additional explicit deopt reasons and removing
the fragile machinery of searching for code comments.
