SHA_Performance_Review_In_UEFI: UEFI SHA1/SHA256 perf tests with C (and asm)

Background of The work: To compare the SHA1/SHA-256 performance in different implementation, different optimization flags and with different compilers(GCC48/GCC5). See how the performance difference in UEFI(Pre-boot environment). As a UEFI developer, while using these CPU intensive algorithms, we need to take into account the performance between them.
