Mitchell Horne 9d61599983 Consolidate machine/endian.h definitions ... This change serves two purposes. First, we take advantage of the compiler provided endian definitions to eliminate some long-standing duplication between the different versions of this header. __BYTE_ORDER__ has been defined since GCC 4.6, so there is no need to rely on platform defaults or e.g. __MIPSEB__ to determine endianness. A new common sub-header is added, but there should be no changes to the visibility of these definitions. Second, this eliminates the hand-rolled __bswapNN() routines, again in favor of the compiler builtins. This was done already for x86 in e6ff6154d2. The benefit here is that we no longer have to maintain our own implementations on each arch, and can instead rely on the compiler to emit appropriate instructions or libcalls, as available. This should result in equivalent or better code generation. Notably 32-bit arm will start using the `rev` instruction for these routines, which is available on armv6+.
