This PR adds the following features: * saturation and float rounding mode decorations, * arithmetic constrained floating-point intrinsics (strict_fadd, strict_fsub, strict_fmul, strict_fdiv, strict_frem, strict_fma and strict_fldexp), * and SPV_INTEL_float_controls2 extension, * using recent improvements of emit-intrinsics step, this PR also simplifies pre- and post-legalizer steps and improves instruction selection.
