This class allows to see the inliner's decisions for better
optimization verifications and tests. To use, use flag
"-passes="print<inline-cost>"".
This is the second attempt to integrate the patch.
The problem from the first try has been discussed and
fixed in D82205.

- Renaming the printer class, flag
- Refactoring
- Changing some tests
This patch is a preparational stage for introducing a new printing pass and new
functionality to the existing Annotation Writer. I plan to extend
this functionality for this tool to be more useful when looking at the inline
process.
-debug-only=inline-cost does not exist in optimized builds without
asserts and therefore the test fails for such configurations.

Add extra diagnostics for the inline cost analysis under
-print-instruction-deltas cl option. When enabled along with
-debug-only=inline-cost it prints the IR of inline candidate
annotated with cost and threshold change per every instruction.
