[PATCH] D13532: [CGP] widen switch condition and case constants to target's register width

Patch updated:

1. Add check for a sign-extended function argument - in that case sext everything instead of zext.
2. Minimized tests - we don't need so many switch cases to show the differences in IR (the larger examples were better for visualizing the asm differences).
3. Added test case for #1.
