Reviewed by Yusuke Suzuki.

Added support to IPInt for a SIMD entrypoint that is used if a function uses SIMD.
Enabled SIMD support in IPInt.
Added dispatch logic to support SIMD instructions.
Added unimplementedInstruction labels for all SIMD instructions (not including relaxed SIMD).

* JSTests/wasm/ipint-tests/ipint-test-simd.js: Added.
