annotate src/bitfcns.cc @ 14631:57e4ff70b7c1

Use more templates in bitwise operators. Death to macros! ☠ * bitfcns.cc: Use standard functional header. (BITOPX): Replace with bitopxx templated function. (bitopx): New templated trampoline function. (BITOP): Replace with bitop function. (Fbitand, Fbitor, Fbitxor): Replace calls to BITOP with calls to bitop.
