Jit64AsmCommon: Use AVX in ConvertDoubleToSingle 

Using AVX we can eliminate another MOVAPS instruction here.

Before:
0F 28 C8                movaps      xmm1,xmm0
66 0F DB 0D CF 2C 00 00 pand        xmm1,xmmword ptr [1F8D283B220h]

After:
C5 F9 DB 0D D2 2C 00 00 vpand       xmm1,xmm0,xmmword ptr [271835FB220h]
