The existing code errors out immediately if the argument is not
"comparable", making it impossible to test a slice, map, and so
on from being compared to nil.
Fix by delaying the "comparable" error check until we encounter
an actual check between two non-comparable, non-nil values.
Note for the future: reflect makes it unnecessarily clumsy
to deal with nil values in cases like this. For instance, it
should be possible to check if a value is nil without stepping
around a panic. See the new functions isNil and canCompare
for my (too expensive) workaround.

There's been plenty of discussion on the usage of these terms in tech.
I'm not trying to have yet another debate. It's clear that there are
people who are hurt by them and who are made to feel unwelcome by their
use due not to technical reasons but to their historical and social
context. That's simply enough reason to replace them.
Anyway, allowlist and blocklist are more self-explanatory than whitelist
and blacklist, so this change has negative cost.
Didn't change vendored, bundled, and minified files. Nearly all changes
are tests or comments, with a couple renames in cmd/link and cmd/oldlink

This had an unexpected effect on html/template, where all data is
implicitly passed to functions: originally untyped nil arguments were
not passed and were thus effectively ignored, but after CL 95215 they
were passed and were printed, typically as an escaped version of "<nil>".
This CL restores some of the behavior of html/template by ignoring
untyped nil arguments passed implicitly to escaper functions.
While eliminating one change to html/template relative to earlier
releases, this unfortunately introduces a different one: originally
values of interface type with the value nil were printed as an escaped
version of "<nil>". With this CL they are ignored as though they were
untyped nil values. My judgement is that this is a less common case.
We'll see.
This CL adds some tests of typed and untyped nil values to
html/template and text/template to capture the current behavior.

golang.org/cl/84480 altered the API for the parse package for
clarity and consistency. However, the changes also broke the
API for consumers of the package. This CL reverts the API
to the previous spelling, adding only a single new exported
symbol.

text/template recently added support for passing untyped nil as function
call arguments, as those would be mixed up with "missing argument"
values before. See CL 95215.
html/template now needs a small change to adapt to that new possibility.
In particular, when printing values as JS bytes, its code was written
under the assumption that the values would never be untyped nil - that
is, the reflect.Value would always be valid.
Short-circuit indirectToJSONMarshaler on an untyped nil, to avoid the
panic and fall back to the existing " null " output. Before this change
and on 1.10, printing a typed nil and an untyped nil resulted in:
null ""
After this change, one will get:
null null
Fixes#24717.
