;; We need a call saved register allocated for the match_scratch, so we use
;; 'l' because all local registers are call saved.
;; ??? I would prefer to use a match_scratch here, but match_scratch allocated
;; registers can't be used for spills. In a function with lots of calls,
;; local-alloc may allocate all local registers to a match_scratch, leaving
;; no local registers available for spills.
