We also renamed `filter` (as a name of a parameter) to `predicate` following the naming suggestion in code review. It's better!
Since it's not part of an attrset, the name can change with no impact to semantics, since it can't be observed with `builtins.functionArgs`.

Synopsis: builtins.functionArgs f
Return a set containing the names of the formal arguments expected by the function f. The value of each attribute is a Boolean denoting whether the corresponding argument has a default value. For instance, functionArgs ({ x, y ?
123}: ...) = { x = false; y = true; }.
"Formal argument" here refers to the attributes pattern-matched by the function. Plain lambdas are not included, e.g. functionArgs (x: ...) = { }.

The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
Replace writeReferencesToFile with writeClosure.
Make writeClosure accept a list of paths instead of a path.
Re-implement with JSON-based exportReferencesGraph interface provided by
__structuredAttrs = true.
Reword the documentation.

In NixOS/nixpkgs#290081 it came to attention that autoPatchelfHook is
one of if not the only hook in Nixpkgs that is a multiline string
expression. Almost all hooks are functions, which guard with something
like `if [ -z "${dontDoTheThing-}" ]; then ...` in the function, or
single-line strings which include that guard inline and then call the
real function, e.g. `if [ -z "${dontDoTheThing-} ]; then doTheThing; fi`.
This commit moves autoPatchelfHook to the former, which seems to be the
most common style now.
swiftc uses cc-wrapper which sets the -march flag on some systems which
breaks the build. This change adds a flag, disableMarch, to cc-wrapper
which disables using the -march flag.

This assumes that downstream users of `buildNpmPackage` would rather our
own built `node_modules` be copied to the output rather than only the
`bundleDependencies` specified in the `package.json` file.
Having the latter behavior seems unexpected and unintuitive, and would
not work as installing from an `npm pack` is intended to (since doing
that would not do a `rebuild` step on those dependencies and it would
skip reifying a full dependency tree).
