  [DSE] Make DSEState non-copyable (NFC)

As it contains a self-reference, the default copy/move ctors
would not be safe.

Move the DSEState::get() method into the ctor to make sure no move
occurs here even without NRVO.

This is a speculative fix for test failures on
llvm-clang-x86_64-expensive-checks-win.
