Improve the performance of long-to-double conversions on ARM.
Use a VMLA instruction instead of VADD & VMUL instructions
in long-to-double conversions on ARM. This change reduces
code size and improves execution times (but does not alter
precision). It trades one temporary FPU register for two
temporary core registers.
