qemu-common: add VEC_OR macro

Browse source 
Intel C Compiler version 15.0.3.187 Build 20150407 doesn't support
'|' function for non floating-point simd operands.

Define VEC_OR macro which uses _mm_or_si128 supported
both in icc and gcc on x86 platform.

Backports commit 34664507c7f038842f20a2c787915680b1fabba2 from qemu
