Increase simd test coverage: 1) Add a new testing mode to force every function to be conservative w.r.t. treating floating point registers as vectors 2) Allow tier-up directly to OMG for SIMD functions 3) Remove extra test options implied when using SIMD. Note that we now assume all functions might use SIMD if the LLInt is disabled. 4) Add new test simd-exception.js
