Subject: Provide LIBRESSL_USE_.*_ASSEMBLY defines.

Make life easier for portable by providing LIBRESSL_USE_.*_ASSEMBLY
defines, which enable/disable assembly for a specific algorithm. This
means that selected platforms can include the assembly files and specify
a define, rather than having to try to patch the crypto_arch.h headers.
