  Log Message:

  [NFCI][CodeGen] DwarfEHPrepare: don't actually pass DTU into simplifyCFG by default

also, don't verify DomTree unless we intend to maintain it.
This is a very dumb think-o, i guess i was even warned about it
by subconsciousness in 4b80647367950ba3da6a08260487fd0dbc50a9c5's
commit message..

Fixes a compile-time regression reported by Martin Storsjö
in post-commit review of 2461cdb41724298591133c811df82b0064adfa6b.

  Changed paths:
    M llvm/lib/Transforms/Utils/SimplifyCFG.cpp

  Log Message:
  -----------
  [SimplifyCFG] Don't actually take DomTreeUpdater unless we intend to maintain DomTree validity

This guards against unintentional mistakes
like the one i just fixed in previous commit.
