* module/ice-9/boot-9.scm (define-values): Use 'generate-temporaries' to
generate a fresh name for 'dummy', to work around the lack of hygiene
for macro-introduced toplevel identifiers. Blackhole 'dummy' to avoid
keeping garbage alive. Add more comments.

* module/texinfo/serialize.scm: Change most uses of 'compile' to
'expand', except where we must avoid it during initial bootstrap
before the module system is loaded. Remove redundant uses of
'compile' where 'expand' is also given. Standardize on the
"(expand load eval)" order of conditions.
* doc/ref/api-macros.texi (Eval When): Explain in detail what each
condition means, including 'expand' which was previously undocumented.
Change the example to use (expand load eval) and recommend that set of
conditions, instead of (compile load eval) which was previously
recommended and shown in the example.
