cf5ec4b4cd When RemoveCopyByCommutingDef is creating additional identity copies, just use 
LiveInterval::MergeValueNumberInto instead of trying to extend LiveRanges and
getting it wrong.

This fixed PR8249 where a valno with a multi-segment live range was defined by
an identity copy created by RemoveCopyByCommutingDef. Some of the live
segments disappeared.

869c188757 Now that the asmprinter itself isn't in the subdir, rename 'AsmPrinter' to 
'InstPrinter' to fall into line with the other MC-ized assembly printer
using targets.

95581657a4 Thread the determination of branch prediction hit rates back through the if-conversion heuristic APIs. For now, 
stick with a constant estimate of 90% (branch predictors are good!), but we might find that we want to provide
more nuanced estimates in the future.

2143c9d321 Rename the AsmPrinter directory to InstPrinter for those targets that have 
been MC-ized for assembly printing. MSP430 is mostly so, but still has the
asm printer and lowering code in the printer subdir for the moment.

e01e38ff1e Remove self-described temporary hack. A bit over a year seems a reasonable 
delay. Anton and PIC16 folks, if this is still good to keep, please go ahead
and add it back in with an updated comment about when would be a good time
to revisit.

a88628cd72 Now that the profitable bits of EnableFullLoadPRE have been enabled by default, rip out the remainder. 
Anyone interested in more general PRE would be better served by implementing it separately, to get real
anticipation calculation, etc.
