Add a DAGCombine xform to fold away redundant float->double->float conversions around sqrt instructions.
I am assured by people more knowledgeable than me that there are no rounding issues in eliminating this.

This fixed <rdar://problem/8197504>.

their call expressions synthetically have the "deduced" types based on their
first argument. We only insert conversions in the AST for arguments whose
values require conversion to match the value type expected. This keeps PR7600
closed by maintaining the return type, but avoids assertions due to unexpected
implicit casts making the type unsigned (test case added from Daniel).

The magic is moved into the codegen for the atomic builtin which inserts the
casts as needed at the IR level to raise the type to an integer suitable for
the LLVM intrinsic. This shouldn't cause any real change in functionality, but
now we can make the builtin be more truly polymorphic.

LoopSplitter be run prior to register allocation.

Entirely for testing purposes at the moment.

  Let AnalysisContext contain a TranslationUnit.
  Let CallEnter refer to an AnalysisContext instead of a FunctionDecl.

Still very much under development. Comments and fixes will be forthcoming.

(This commit includes some small tweaks to LiveIntervals & LoopInfo to support the splitter)

any command line paramater changed the register allocation produced by
PBQP.

Turns out variety is not the spice of life.

Fixed some comparators, added others. All good now.

constant replacement which was botching its handling of
types.  Use of getType() instead of getRawType() was causing
the type map in constant folding to be updated wrong.
