fa44725233 Add InEdges (edges from header to the loop) in Loop Branch Heuristics, so
there is no frequency difference whether condition is in the header or in
the latch.

5116ff671f SCEV: Added a data structure for storing not-taken info per loop
exit. Added an interfaces for querying either the loop's exact/max
backedge taken count or a specific loop exit's not-taken count.

40c7e4142e There are two ways to map a variable to its lexical scope. Lexical scope information is embedded in MDNode describing the variable. It is also available as a part of DebugLoc attached with DBG_VALUE instruction. DebugLoc attached with an instruction is less reliable in optimized code so use information embedded in the MDNode.

71997f303e Teach IVUsers to stop at non-affine expressions unless they are both
outside the loop and reducible.

This more completely hides them from LSR, which isn't usually able to
do anything meaningful with non-affine expressions anyway, and this
consequently hides them from SCEVExpander, which is acutely unprepared
for non-affine expressions.

Replace test/CodeGen/X86/lsr-nonaffine.ll with a new test that tests
the new behavior.

This works around the bug in PR10117 / rdar://problem/9633149, and is
generally an improvement besides.

b065b06c12 Revamp the "ConstantStruct::get" methods. Previously, these were scattered
all over the place in different styles and variants.  Standardize on two
preferred entrypoints: one that takes a StructType and ArrayRef, and one that
takes StructType and varargs.

In cases where there isn't a struct type convenient, we now add a
ConstantStruct::getAnon method (whose name will make more sense after a few
more patches land).  

It would be "really really nice" if the ConstantStruct::get and 
ConstantVector::get methods didn't make temporary std::vectors.
