[JSC] Make double constant materialization better
https://bugs.webkit.org/show_bug.cgi?id=279615
rdar://135908300
Reviewed by Keith Miller.
This change is preparation for the further FP related optimizations, but
let's first clean up things to make them better. This patch makes double
constant materialization better for our CPUs.
