preserves LCSSA form out of ScalarEvolution and into the LoopInfo
class. Use it to check that SimplifyInstruction simplifications
are not breaking LCSSA form. Fixes PR8622.

simplify the second copy of the loop which may be dead or not,
but is probably a constant now. This fixes PR6879

Move the dominator verification code out of special code embedded within2009-09-28T00:27:48ZDan Gohmangohman@apple.com2009-09-28T00:27:48Zurn:sha1:9450b0e1a6154192ca597ad27f8eb6e6e807f7a4
the PassManager code into a regular verifyAnalysis method.
Also, reorganize loop verification. Make the LoopPass infrastructure
call verifyLoop as needed instead of having LoopInfo::verifyAnalysis
check every loop in the function after each looop pass. Add a new
command-line argument, -verify-loop-info, to enable the expensive
full checking.
