v8.1.0736 made some changes for making some emsgs more specific.
Includes the change for Test_lambda_fails() in test_lambda.vim.
Adjust relevant functionaltests to expect the new emsgs.
This patch has been fully ported in my Blob port PR, but it hasn't been
merged yet, so just use what we need from it for now.
Required for v8.1.1821.
Problem: Cannot see the selection type in :reg output. (Ayberk Aydın)
Solution: Add c/l/b. (Christian Brabandt, closesvim/vim#5110, closesvim/vim#4546)

Patch v8.1.0999 is not ported so ":registers" does not omit register 1.
