ulan@chromium.org 4485930247 ARM: Try to avoid VMSR instruction and drop redundant VCVT 
We were doing a redundant VCVT operation in MacroAssembler::EmitECMATruncate.
Also, setting the FPSCR exception flags is expensive on some CPUs, wo we should
try to avoid it if we can.

Thanks to Rodolph Perfetta for the input on this!
