stub is added to provide __cpu_simple_lock and __cpu_simple_lock_try via
thumb interwork support.  It is compiled with -mno-thumb.

82db4b9858 Replace consttime_bcmp/explicit_bzero by consttime_memequal/explicit_memset. 
consttime_memequal is the same as the old consttime_bcmp.
explicit_memset is to memset as explicit_bzero was to bcmp.

Passes amd64 release and i386/ALL, but I'm sure I missed some spots,
so please let me know.

d4c5b4f6c6 Add support for __ARM_ARCH_EXT_IDIV__ which is set for those cores 
with hardware divide instructions.  Note that gcc 4.5.x doesn't support
this so this is just latent.  gcc 4.7.x does.

e0ac190e1e Provide explicit LC_C_LOCALE accessor and drop the various NULL checks. 
Provide LC_GLOBAL_LOCALE in a way that works with all locale functions.
Merge constant data used by the initial global locale and the C locale.
Drop function call layer for _current_locale() and directly return the
locale reference, not a pointer to it. Use protected access for global
variables, so that libc references can avoid the GOT overhead.

c7dafd4acd Do not use isalpha here, since we explicitly only support the Portable 
Character Set as base and in theory a locale could define a ASCII
control character as letter, resulting in negations. Also avoid isdigit
here to give the compiler a better chance of deciding whether an
unsigned compare or a jump table is a better option, both are very
likely better choices than the memory indirection.
