handy.h: New #define to use new bit

This creates a new macro for use by regcomp to test the new bit
regarding non-ascii folds.

Because the semantics may change in the future to deal with multi-char
folds, the name of the macro is unwieldy and specific enough that no one
should be tempted to use it.
