David Green	f67d93dc23	[ARM] Constant long shift combines This changes the way that asrl and lsrl intrinsics are lowered, going via a the ISEL ASRL and LSLL nodes instead of straight to machine nodes. On top of that, it adds some constant folds for long shifts, in case it turns out that the shift amount was either constant or 0.

[ARM] Constant long shift combines

This changes the way that asrl and lsrl intrinsics are lowered, going
via a the ISEL ASRL and LSLL nodes instead of straight to machine nodes.
On top of that, it adds some constant folds for long shifts, in case it
turns out that the shift amount was either constant or 0.
