Dan Gohman cd83870faf 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.

Dan Gohman 0141c13b22 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.

Dan Gohman accaca5604 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.

Sebastian Redl ae8cbb7220 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.

Rafael Espindola 235457ca7f Clone and restore the module being reduced in 
ReduceMiscompilingFunctions::TestFuncs. This makes the test functional
(i.e., no side effects).

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.

Nick Lewycky a3f7dcd069 Don't pass -export-dynamic to the linker on Cygwin and MinGW. These platforms

Douglas Gregor f2430ba223 Start removing the use of smart pointers from the Parse/Sema 
interaction, by effectively defaulting to
DISABLE_SMART_POINTERS. We're embracing the model where all AST nodes
are ASTContext-allocated and live as long as the ASTContext lives.
