Hal Finkel 9ae5b7a40a [PowerPC] Mark zext of a small scalar load as free

This initial implementation of PPCTargetLowering::isZExtFree marks as free
zexts of small scalar loads (that are not sign-extending). This callback is
used by SelectionDAGBuilder's RegsForValue::getCopyToRegs, and thus to
determine whether a zext or an anyext is used to lower illegally-typed PHIs.
Because later truncates of zero-extended values are nops, this allows for the
elimination of later unnecessary truncations.

Fixes the initial complaint associated with PR22120.

Reverting r225319; since there is a folder named Examples, attempting to add a target of the same name causes problems for IDEs like Visual Studio.

examples

Manually specify the folder that Kaleidescope should reside in for CMake-produced solutions that care about such things (like MSVC). This takes the Kaleidescope target out of the root solution folder and places it into the Examples folder where it belongs.
