Benchmarks - pmatch, pcons, and other core internal(possibly)

[SeungheonOh]

pcons and pmatch are sude very frequently, hence changes in their performance can affect overall performance significantly. Benchmark with through cases for each of their usecases is need to ensure performance degradation my mistake.

Need to check: pmatch and pcons for each of encodings, both SOP types(Structs) and NP types(Records). Each types needs to check cases when some fields were used or not, and if each fields were used single time or multiple times.
