cdaa08e706 Re-apply r80926, with fixes: keep the domtree informed of new blocks 
that get created during loop unswitching, and fix SplitBlockPredecessors'
LCSSA updating code to create new PHIs instead of trying to just move
existing ones.

Also, optimize Loop::verifyLoop, since it gets called a lot. Use
searches on a sorted list of blocks instead of calling the "contains"
function, as is done in other places in the Loop class, since "contains"
does a linear search. Also, don't call verifyLoop from LoopSimplify or
LCSSA, as the PassManager is already calling verifyLoop as part of
LoopInfo's verifyAnalysis.

d7d08596d6 When emitting a label for a PostCall safe point, the machine 
instruction to insert before can be end(). getDebugLoc on
end() returns an invalid value, therefore use the debug
loc of the call instruction, and give it to InsertLabel.

893fbc4fec add a bunch more evil lowering code to work around various :subreg32 modifiers

2e9f3b2865 fix PR4767, a crash because fp stackifier visited blocks in 
depth first order, so it wouldn't process unreachable blocks.
When compiling at -O0, late dead block elimination isn't done
and the bad instructions got to isel.

12d0bc749f instcombine transforms vector loads that are only used by 
extractelement operations into a bitcast of the pointer,
then a gep, then a scalar load.  Disable this when the vector
only has one element, because it leads to infinite loops in
instcombine (PR4908).

This transformation seems like a really bad idea to me, as it
will likely disable CSE of vector load/stores etc and can be
better done in the code generator when profitable.  This
goes all the way back to the first days of packed types,
r25299 specifically.

I'll let those people who care about the performance of vector
code decide what to do with this.

8d3fc4bfab Simplify from my last change. Assert1 is a macro that makes its caller return, 
so "Assert1(isa<>); cast<>" is a valid idiom.

Actually check the PHI node's odd-numbered operands for BasicBlock-ness, like
the comment said.

5536fa68c5 Verify types. Invalid types can be constructed when assertions are off. 
Make the verifier more robust by avoiding unprotected cast<> calls. Notably,
Assert1(isa<>); cast<> is not safe as Assert1 does not terminate the program.

572ecc26b6 Fix a thinko: When lowering fneg with xor, bitcast the operands 
from floating-point to integer first, and bitcast the result
back to floating-point. Previously, this test was passing by
falling back to SelectionDAG lowering. The resulting code isn't
as nice, but it's correct and CodeGen now stays on the fast path.
