Fix SCEVExpander::visitAddRecExpr so that it remembers the induction variable
...
it inserted rather than using LoopInfo::getCanonicalInductionVariable to
rediscover it, since that doesn't work on non-canonical loops. This fixes
infinite recurrsion on such loops; PR7562.

Remove LCSSA's bogus dependence on LoopSimplify and LoopSimplify's bogus
...
dependence on DominanceFrontier. Instead, add an explicit DominanceFrontier
pass in StandardPasses.h to ensure that it gets scheduled at the right
time.
Declare that loop unrolling preserves ScalarEvolution, and shuffle some
getAnalysisUsages.
This eliminates one LoopSimplify and one LCCSA run in the standard
compile opts sequence.

Fix (at least) quadratic worst-case complexity in DominanceFrontier::splitBlock:
...
don't visit all blocks in the function, and don't iterate over the split blocks'
predecessor lists for each block visited.
Also, remove the special-case test for the entry block. Splitting the entry
block isn't common enough to make this worthwhile.
This fixes a major compile-time bottleneck which is exposed now that
LoopSimplify isn't being redundantly run both before and after
DominanceFrontier.

Make sure that implicit qualification and derived-to-base conversions of xvalues preserve xvalue-ness. Unfortunately I have no idea how to test this property; there doesn't seem to be a syntactical construct that triggers such a conversion and still allows the distinction between prvalues and xvalues to be made.

ReduceMiscompilingFunctions::TestFuncs. This makes the test functional

Before we would end up using dead functions if a pass decided to remove them
(inline for example) and we would also keep broken functions and conclude that
that a single function was enough to reproduce the bug.
