Clarify infinity_f preprocessor definition. (issue2099043)

Reviewers: ,

Message:
I have another tiny clarity rewrite for code.

Description:
Clarify infinity_f preprocessor definition.

The old code confuses various style programs, including our own
fixcc.py (it produces un-compilable code!).  In particular:
-----
const Real infinity_f
= #ifdef
-----
which makes gcc unhapy.

The new format is easy for style programs to deal with, still
compiles, and is IMO just as clear anyway.
