gh-124951: Optimize base64 encode & decode for an easy 2-3x speedup [no SIMD] (GH-143262)
...
Optimize base64 encoding/decoding by eliminating loop-carried dependencies. Key changes:
- Add `base64_encode_trio()` and `base64_decode_quad()` helper functions that process complete groups independently
- Add `base64_encode_fast()` and `base64_decode_fast()` wrappers
- Update `b2a_base64` and `a2b_base64` to use fast path for complete groups
Performance gains (encode/decode speedup vs main, PGO builds):
```

Zen2: 1.2x/1.8x 1.7x/2.8x 1.5x/2.8x
Zen4: 1.2x/1.7x 1.6x/3.0x 1.5x/3.0x [old data, likely faster]
M4: 1.3x/1.9x 2.3x/2.8x 2.4x/2.9x [old data, likely faster]
RPi5-32: 1.2x/1.2x 2.4x/2.4x 2.0x/2.1x
```
Based on my exploratory work done in https://github.com/python/cpython/compare/main...gpshead:cpython:claude/vectorize-base64-c-S7Hku
See PR and issue for further thoughts on sometimes MUCH faster SIMD vectorized versions of this.

Remove untrue part of `__import__` replacement docs
The original statement effectively says that replacing `__import__` at global scope affects import statements, and not only that, but only import statements within the rest of the executing module. None of that has been true since at least Python 2.7, I think.
This was likely missed in python/cpython#69686 .
