Various codegen tests failing

[latkin]

I'm seeing the following failures on master. Have not dug in to see what the delta is.

Optimizations\GenericComparison #  (Compare07.fs - NetFx40)
Optimizations\GenericComparison #  (Compare10.fs - NetFx40)
Optimizations\GenericComparison #  (Equals06.fs - NetFx40)
Optimizations\GenericComparison #  (Equals09.fs - NetFx40)
Optimizations\GenericComparison #  (Hash09.fs - NetFx40)
Optimizations\GenericComparison #  (Hash12.fs - NetFx40)

I dare say that would be #513 - that was slurped in relatively recently? Lots of stuff around equality gets inlined, so it could end up with different codegen? But I see green on master build? Are you doing something extra?

@manofstick Not all tests are run by CI. I'm going to track all current test failures on master with bug #915 and close this.

@manofstick Please see #944 (comment) and take a careful look at the tailcalls that have been removed.

For example this one: https://github.com/Microsoft/visualfsharp/pull/944/files#diff-60d0249459018d317436fa8662d9701eL598
