Package rangefunc rewrites range-over-func to code that doesn't use range-over-funcs.
Rewriting the construct in the front end, before noder, means the functions generated during
the rewrite are available in a noder-generated representation for inlining by the back end.

The basic idea is to rewrite

GODEBUG=gocachehash=1 causes the go command to print the inputs
for all of the content hashes it uses to construct cache lookup keys.
The output is voluminous but can be useful for debugging the cache.

GODEBUG=gocachetest=1 causes the go command to print details of its
decisions about whether to reuse a cached test result.
