48638f63ba LoopSplitter - intended to split live intervals over loop boundaries. 
Still very much under development. Comments and fixes will be forthcoming.

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

thus is a much more meaningful name.

444c76a3b1 Revert r108369, sorting llvm.dbg.declare information by source position, 
since it doesn't work for front-ends which don't emit column information
(which includes llvm-gcc in its present configuration), and doesn't
work for clang for K&R style variables where the variables are declared
in a different order from the parameter list.

Instead, make a separate pass through the instructions to collect the
llvm.dbg.declare instructions in order. This ensures that the debug
information for variables is emitted in this order.

ffbae6ad52 Split -enable-finite-only-fp-math to two options: 
-enable-no-nans-fp-math and -enable-no-infs-fp-math. All of the current codegen fp math optimizations only care whether the fp arithmetics arguments and results can never be NaN.

07ef07c202 Make the order in which variables are described in debug information 
independent of the order that isel happens to visit the dbg_declare
intrinsics. This fixes a bug in which the formal arguments were
being printed in reverse order, now that fast isel is going bottom up.

18711b19c9 Don't propagate debug locations to instructions for materializing

which get the same line, and this confuses debug info.

9772b3e74f rotate CallInst operands 
with this commit the callee moves to the end of
the operand array (from the start) and the call
arguments now start at index 0 (formerly 1)

this ordering is now consistent with InvokeInst

this commit only flips the switch,
functionally it is equivalent to
r101465

I intend to commit several cleanups after a few
days of soak period
