2659ac01be Add Sha2 functions 
We take the fastest time measurement taken across multiple runs. Tested
across multiple compiler flags and the best chosen.

Merge pull request #686 from zig-lang/md5-sha1 
Add Md5 and Sha1 functions

51fdbf7f8c Add Md5 and Sha1 hash functions 
Some performance comparisons to C.

We take the fastest time measurement taken across multiple runs.

The block hashing functions use the same md5/sha1 methods.

In short, zig provides pretty useful tools for writing this sort of
code. We are in the lead against clang (which uses the same LLVM
backend) with us being slower only against md5 with GCC.

3268276b58 the same string literal codegens to the same constant 
this makes it so that you can send the same string literal
as a comptime slice and get the same type

closes #672

the crash and compile errors are fixed but structs
inside functions still get named after the functions
they're in. this will be fixed later.
