ea454d8687 Undeprecate isNull
There's no good reason to deprecate it:
- For consistency reasons it should continue to exist, such that all
primitive types have a corresponding `builtins.is*` primop.
- There's no implementation cost to continuing to have this function
- It costs users time to try to migrate away from it, e.g.
  https://github.com/NixOS/nixpkgs/pull/219747 and https://github.com/NixOS/nixpkgs/pull/275548
- Using it can give easier-to-read code like `all isNull list`

Move down fallback targets in `Makefile`

26d60b837c Move down fallback targets in Makefile
This ensures `lib.mk` still defines `default` as the first target. This
fixes some builds.

2b0e95e7aa use singleton expr to generate black hole errors
this also reduces forceValue code size and removes the need for
hideInDiagnostics. coopting thunk forcing like this has the additional
benefit of clarifying how these errors can happen in the first place.

f9db4de0f3 force-inline forceValue
forceValue is extremely hot. interestingly adding likeliness annotations
to the branches does not seem to make a difference.

69ed4aee61 remove lazy-pos forceValue
almost all uses of this are interactive, except for deepSeq. deepSeq is
going to be expensive and rare enough to not care much about, and
Value::determinePos should usually be cheap enough to not be too much of
a burden in any case.

f9aee2f2c4 don't malloc/memset posix accessor buffer
it's relatively small and fits on the stack nicely, and we don't need it
initialized either.

b78e77b34c use custom location type in the parser
~1% parser speedup from not using TLS indirections, less on system eval.
this could have also gone in flex yyextra data, but that's significantly
slower for some reason (albeit still faster than thread locals).

2e0321912a use aligned flex tables
~2% speedup on parsing without eval, less (but still significant) on
system eval. having flex generate faster parsers leads to very strange
misparses. maybe re2c is worth investigating.

78353deb02 encode black holes as tApp values
checking for isBlackhole in the forceValue hot path is rather more
expensive than necessary, and with a little bit of trickery we can move
such handling into the isApp case. small performance benefit, but under
some circumstances we've seen 2% improvement as well.

This is because `mktemp` returns a path like
`/var/folders/z5/fclwwdms3r1gq4k4p3pkvvc00000gn/T/tmp.qDY24l6bIM`,
where `/var` is a symlink to `/private/var`.

Then, we attempt to use that path as a `builder`, which errors because
symlinks are impure or whatever.

Anyways, we can fix this by using `realpath "$(mktemp)"` instead of
`mktemp` directly.

NB: This error doesn't seem to happen when I run the tests through `nix
flake check`. I'm not sure if Nix does something to `TMP` in that case.

1f7b62f123 Use nix daemon in the test suite
As part of the CLI stabilization effort, the last remaining checkbox (at
the moment) for `nix daemon` is that it "needs testing". This implements
the proposal of using `nix daemon` in place of `nix-daemon` in the test
suite.

7feabf7d44 Split --disable-tests, fix cross builds
It might seem obnoxious to have yet more configure flags, but I found
controlling both the unit and functional tests with one flag was quite
confusing because they are so different:

- unit tests depending on building, functional tests don't (e.g. when
  we test already-built Nix)

- unit tests can be installed, functional tests cannot

- unit tests neeed extra libraries (GTest, RapidCheck), functional
  tests need extra executables (jq).

- unit tests are run by `make check`, functional tests are run by `make
  installcheck`

Really on a technical level, they seem wholly independent. Only on a
human level ("they are both are tests") do they have anything in common.

I had messed up the logic in cross builds because of this. Now I
split the flag in two (and cleaned up a few other inconsistencies), and
the logic fixed itself.
