Harmonize OSX/iOS configuration; enable compiling for iPhone simulator
Darwin setup would assume i386/x86_64 was OS X, while arm/arm64 was iOS.
The iPhone simulator, however, breaks this assumption, covering both
i386 and x86_64 (depending on the simulated device).
With this patch <TargetConditionals.h> is pulled in and TARGET_OS_IPHONE
used to detect an iOS target -- both device and simulator.
Otherwise, #defines were moved to keep Darwin setup similar across
i386/x86_64/arm/arm64, making GC_DONT_REGISTER_MAIN_STATIC_DATA and
TARGET_OS_IPHONE options respected across the board.

Modified darwin_stop_world.c to use an arm_unified_thread_state_t struct to
store a thread's state when compiling against the iOS 7/8 SDK. Without this
patch GC_stack_range_for() crashes when running a 32-bit app on iOS 64-bit.
The old code passed an arm_thread_state_t and ARM_THREAD_STATE to
thread_get_state(). ARM_THREAD_STATE is the same as ARM_UNIFIED_THREAD_STATE
on iOS 7/8 and thread_get_state() actually expects an
arm_unified_thread_state_t. On iOS 32-bit it looks like thread_get_state()
only touches the first bytes corresponding to the size of arm_thread_state_t
so no crash there. On iOS 64-bit however it seems thread_get_state() writes to
the full arm_unified_thread_state_t which meant it would overflow the stack
allocated struct passed to it and mess up other values on the stack leading to
a crash later on.

Workaround Linux NTPL lock elision bug.
glibc 2.19 on Linux x86-64 platforms includes support for lock elision,
by using Intel's TSX support when it is available. Without modifying an
application this converts suitable critical sections that use mutex into
transactional memory critical sections. See http://lwn.net/Articles/534758/
If a problem occurs that means that transactional memory can't be used, such
as a system call or buffer overflow, the pthreads implementation will catch
this error and retry the critical section using a normal mutex.
I noticed that since upgrading glibc that programs using Boehm GC crash, one
of these crashes was an assertion that the owner field of a mutex was
invalid. The assertion was generated by the pthreads implementation.
I believe that there is a bug in glibc that when a mutex cannot be used
safely for transactions that some series of events causes it's owner field
to be set incorrectly (or cleared when it shouldn't be).
I've found that I can work around this problem by having Boehm GC use an
error checking mutex, which I believe doesn't use lock elision and in my
testing doesn't crash.
XXX: This work-around mostly works except for linking the feature detection
in configure.ac to the conditional compilation in pthread_support.c as there
isn't an obvious way to make it work for automake and Makefile.direct.
Could I have some help updating the build system please?
