Customer Impact
This is a change to revert a workaround for a compiler bug which was incorrectly generating popcnt SSE4 instructions.
Regression
[If yes, specify when the regression was introduced. Provide the PR or commit if known.]
Testing
Tested manually on a non-SSE4 machine.
Risk
[Low.] since it's simply a revert of a previous workaround to disable optimizations for a few methods.
