X87: [simd.js] Single SIMD128_VALUE_TYPE for all Simd128Values.

port f4c079d4 (r30107).

This is the appendix of 458dfe3b943edb3238917edfe9e2dde326cd1adb which misses
one modified file.

original commit message:

    There's no need to have one InstanceType per SIMD primitive type (this
    will not scale long-term).  Also reduce the amount of code duplication
    and make it more robust wrt adding new SIMD types.
