[libc] Optimized version of memmove
This implementation relies on storing data in registers for sizes up to 128B.
Then depending on whether `dst` is less (resp. greater) than `src` we move data forward (resp. backward) by chunks of 32B.
We first make sure one of the pointers is aligned to increase performance on large move sizes.

[libc] fix memcpy builtin looping
previously, memcpy could get stuck in a loop, calling __builtin_memcpy
which would redirect to itself. This patch removes that path.

[libc] apply new lint rules
This patch applies the lint rules described in the previous patch. There
was also a significant amount of effort put into manually fixing things,
since all of the templated functions, or structs defined in /spec, were
not updated and had to be handled manually.

[libc] Optimize Loop strategy
Since the precondition for loop is `size >= T::kSize` we always expect
at least one run of the loop. This patch transforms the for-loop into a
do/while-loop which saves at least one test.
We also add a second template parameter to allow the Tail operation to
differ from the loop operation.

Resubmission of D100646 now making sure that we handle cases were `__builtin_memcpy_inline` is not available.
Original commit message:
Each of these elementary operations can be assembled to support higher order constructs (Overlapping access, Loop, Aligned Loop).
The patch does not compile yet as it depends on other ones (D100571, D100631) but it allows to get the conversation started.
A self-contained version of this code is available at https://godbolt.org/z/e1x6xdaxM
