Only record IVUsers that are dominated by simplified loop
headers. Otherwise SCEVExpander will crash while looking for a
preheader.

I previously tried to work around this in LSR itself, but that was
insufficient. This way, LSR can continue to run if some uses are not
in simple loops, as long as we don't attempt to analyze those users.

Don't try to create "store atomic" instructions of non-integer types; they aren't supported at the moment.  PR12040.

Spacing fixes. Mostly aligning arguments that spilled onto next line with the opening parenthese instead of 2 spaces in.

on our internal nightly testers.  So, basically revert r152486 again.

Abbreviated original commit message:
Implement a more intelligent way of spilling uses across an invoke boundary.

It looks as if Chander's inlining work, r152737, exposed an issue.

Don't know if it is an anathema to include '#' in the warning name.  I'm fine
with changing it, but this was the most obvious name.

Remove unused field NumVariable from Filter class. Even it was needed the same result could be found with VariableInstructions.size(). Also fix some typos in comments.

In InstCombiner::visitOr, make sure we reverse the operand swap used for checking for or-of-xor operations after those checks; a later check expects that any constant will be in Op1.  PR12234.

Revert r152613 (and r152614), "Inline the d'tor and add an anchor instead." for workaround of g++-4.4's miscompilation.

It caused MSP430DAGToDAGISel::SelectIndexedBinOp() to be miscompiled.

[analyzer] Remove AggExprVisitor, a dead class that assisted in visiting C++ expressions with a "base object", because the CFG is now linearized.

The only use of AggExprVisitor was in #if 0 code (the analyzer's incomplete C++ support), so there is no actual behavioral change anyway.
