Tobias Grosser 0efe7b620e Revert "[IndVarSimplify] Rewrite loop exit values with their initial values from loop preheader"
Commit 251839 triggers miscompiles on some bots:

http://lab.llvm.org:8011/builders/perf-x86_64-penryn-O3-polly-fast/builds/13723

(The commit is listed in 13722, but due to an existing failure introduced in
13721 and reverted in 13723 the failure is only visible in 13723)

To verify r251839 is indeed the only change that triggered the buildbot failures
and to ensure the buildbots remain green while investigating I temporarily
revert this commit. At the current state it is unclear if this commit introduced
some miscompile or if it only exposed code to Polly that is subsequently
miscompiled by Polly.
