94af8a8268 Delete redundant tests 
The old tests were hacky and did not cover nearly as many cases as the new tests do.

Move from an "asm" flag to a "no-asm" feature flag (#386) 
* Use a no-asm feature instead of an asm feature

This works better as core/alloc/std have trouble supporting default
featues in this crate.

Signed-off-by: Joe Richey <joerichey@google.com>

* Have no-asm disable arm assembly intrinsics

* memcpy: Create separate memcpy.rs file

Signed-off-by: Joe Richey <joerichey@google.com>

This allows comparing the "normal" implementations to the
implementations provided by this crate.

* mem: Add REP MOVSB/STOSB implementations

The assembly generated seems correct:
