Speed up lookup in redisplay--variables

* lisp/frame.el (redisplay--variables): Make it a hash-table.

* src/xdisp.c (maybe_set_redisplay): Access redisplay--variables
as a hash-table.  This speeds up this function by an order of
magnitude: where previously a setq was slowed down by 100% by
introducing the maybe_set_redisplay test, it is now only 5%
slower.
(syms_of_xdisp) <redisplay--variables>: Doc fix.
