[ARM] Assembly versions of MD5Transform added to hash package
Summary
This merge request, building on !486 (merged) and !497 (merged), provides assembly-optimised versions of the MD5 hash functions in the hash
package for Arm.
What is the current bug behavior?
N/A
What is the behavior after applying this patch?
On Arm architectures, the provided MD5 algorithm should now be significantly faster than the Pascal fallback.
Relevant logs and/or screenshots
Speed increase on arm-linux:
MD5 of a million "a" symbols
Average time taken = 4.392 ms - Pascal
Average time taken = 3.253 ms - ARM Assembly
Additional Notes
While MD5 is cryptographically broken, it is still widely used as a checksum, so it makes sense to provide a fast implementation.
