Performance regression in base64-bytestring caused by dmd-anal regression.
base64-bytestring is about twice as slow on ghc_head than on 8.8
See also the discussion here: https://github.com/emilypi/base64/issues/3
This seems like it could be a result of the NCG changes I made recently.
Steps to reproduce
Run the benchmark suite of https://github.com/andrewthad/base64-bytes
Performance should be equal or better.
Various. Tested on Linux and Windows
