Craig Topper d39e7102a2 [InstCombine] Prevent InstCombine from triggering an extra iteration if something changed in the initial Worklist creation 
Summary:
If the Worklist build causes an IR change this change flag currently factors into the flag for running another iteration of the iteration loop. But only changes during processing should trigger another loop.

This patch captures the worklist creation change flag into the outside the loop flag currently used for DbgDeclares and only sends that flag up to the caller. Rerunning the loop only depends on IC.run() now.

This uses the debug output of InstCombine to determine if one or two iterations run. I couldn't think of a better way to detect it since the second spurious iteration shoudn't make any visible changes. Just wasted computation.

I can do a pre-commit of the test case with the CHECK-NOT as a CHECK if this is an ok way to check this.

This is a subset of D31678 as I'm still not sure how to verify the analysis behavior for that.

dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
