[JSC] ConstFloat / ConstDouble Store should be converted to Const32 / Const64
Store in B3

Reviewed by Keith Miller.
Materializing Const32 / Const64 in GPR is cheaper. So let's convert
Store(ConstDoubleValue, address) / Store(ConstFloatValue, address)
to Store(Const64Value, address) / Store(ConstFloatValue, address). If the
constant value is zero, then ARM64 can further use zero register
for that.
