```
Revert "std: optimize hash_map probe loop condition"

This reverts commit 11803a3a569205d640c7ec0b0aedba83f47a6e64.

Observations from the performance dashboard:
 * strictly worse in terms of CPU instructions
 * slightly worse wall time (but this can be noisy)
 * sometimes better, sometimes worse for branch predictions

Given that the commit was introducing complexity for optimization's
sake, these performance changes do not seem worth it.
