Implemented #1573. All functions marked as "used" will be automatically added to EXPORTED_FUNCTIONS.
getting some initial set of x86 intrinsics mapped to JS SIMD ops; update existing SIMD code to use updated JS SIMD API (SIMD.type.op instead of SIMD.op & SIMD.opu32; int32x4 instead of uint32x4); bug fix: right type of withX() for int32x4 initialization; bug fix: splat(0) instead of zero() for int32x4 initialization
