This reverts commit f2fbdf76d8d07f6a0fbd97825cbc533660d64a37. As noted in the post-commit thread: https://reviews.llvm.org/rGf2fbdf76d8d0 ...this can obscure a min/max pattern where the components have extra uses. We can show that the problem is independent of this change with a slightly modified source example, so this revert just delays/reduces the need to fix the real problem. We need to improve our analysis of negation or -- more generally -- subtraction using patches like D77230 or D68408.
