make new math code compatible with unused variable warning/error
commit b50d315fd23f0fbc4c11e2583801dd123d933745 introduced fp_force_eval implemented by default with a dead store to a volatile variable. unfortunately introduces warnings with -Wunused-variable and breaks the ability to use -Werror with the default warning options set by configure when warnings are enabled. we could just call fp_barrier instead, but that results in a spurious load after the store due to volatile semantics. the fix committed here avoids the load. it will still produce warnings without -Wno-unused-but-set-variable, but that's part of our default warning profile, and there are already other locations in the source where an unused variable warning will occur without it.
