2021-06-01	Reland - Report coverage `0` of dead blocks	Rich Kadel	-1/+1
	Fixes: #84018 With `-Z instrument-coverage`, coverage reporting of dead blocks (for example, blocks dropped because a conditional branch is dropped, based on const evaluation) is now supported. Note, this PR relands an earlier, reverted PR that failed when compiling generators. The prior issues with generators has been resolved and a new test was added to prevent future regressions. Check out the resulting changes to test coverage of dead blocks in the test coverage reports in this PR.

2021-05-01	Report coverage `0` of dead blocks	Rich Kadel	-1/+1
	Fixes: #84018 With `-Z instrument-coverage`, coverage reporting of dead blocks (for example, blocks dropped because a conditional branch is dropped, based on const evaluation) is now supported. If `instrument-coverage` is enabled, `simplify::remove_dead_blocks()` finds all dropped coverage `Statement`s and adds their `code_region`s as `Unreachable` coverage `Statement`s to the `START_BLOCK`, so they are still included in the coverage map. Check out the resulting changes in the test coverage reports in this PR.

2020-10-21	Introduce a temporary for discriminant value in MatchBranchSimplification	Tomasz Miąsko	-8/+22
	The optimization introduces additional uses of the discriminant operand, but does not ensure that it is still valid to evaluate it or that it still evaluates to the same value. Evaluate it once at original position, and store the result in a new temporary.
2020-10-20	Disable MatchBranchSimplification	Tomasz Miąsko	-0/+7
	This optimization can result in unsoundness, because it introduces additional uses of a place holding the discriminant value without ensuring that it is valid to do so.
