This change adds a criterion-enabled benchmark, x64-evex-encoding, to compare the performance of the builder pattern used to encode EVEX instructions in the new x64 backend against the function pattern used to encode EVEX instructions in the legacy x86 backend. At face value, the results imply that the builder pattern is faster, but no efforts were made to analyze and optimize these approaches further.
