JIT: Performance fix for const doubles
Some recent Arm processors take a performance hit when
creating a floating point double by loading it as a pair of singles.
Legacy code to support soft floating point doubles as a pair of core
registers loaded double immediates in this way.
With the CL, we handle double immediates as a single unit.
(cherry-pick of c8129911e598ad0ca8d7b31012444ab6ce8bce45.)
