    • Fix AMD cpu detection. · e51b4ef7 
      Currently we take generic/default code-path on AMD due to misspelling.
Mostly helps with crc+memcpy:

      Add a new API for `extract_and_get_next()` in b-tree that returns both the extracted node and an iterator to the next element in the container.

Motivation: it can be useful, when calling `extract` to maintain an iterator next to the location of the extracted element. `std::set`, et al. allow for this because they have iterator stability. `absl::{flat,node}_hash_{set,map}` allow for this because they are guaranteed not to rehash when elements are removed so they also have iterator stability across calls to `extract()`. But b-tree doesn't support this use case without this API because removing elements can cause rebalancing, which invalidates iterators. We can get the next iterator without this API using `lower_bound(node_handle.value())`, but that requires an extra lookup.

    • Remove absl/time/internal/zoneinfo.inc. It was used to guarantee · d6fa16c8 
      availability of a few timezones for "time_test" and "time_benchmark",
but (file-based) zoneinfo is now secured via existing Bazel data/env
attributes, or new CMake environment settings.

This also avoids the need for employing the CCTZ zone-info-source
extension mechanism (which is a win).
