Alexander Potapenko 046ecc06be Wrap CFStringCreateCopy to prevent copying constant CF strings.
This should fix http://code.google.com/p/address-sanitizer/issues/detail?id=10

Alexander Potapenko f9392011c8 Add a test for CFStringCreateCopy.
Normally this function should not create copies of constant strings, but it does when the default CFAllocator
is replaced (e.g. under AddressSanitizer)

This test is related to http://code.google.com/p/address-sanitizer/issues/detail?id=10

Evgeniy Stepanov 84c44a8b8b EHABI-based stack trace on ARM.
The change removes the unused FLAG_fast_unwind, and forces EHABI-based unwind
on ARM, and fast (FP-based) unwind everywhere else.

Alexander Potapenko bd53f597de This patch adds two methods, __asan_allocate_island and __asan_deallocate_island
and switches our interceptors to using them instead of the default
vm_allocate-based approach used by mach_override_ptr.

To simplify the code, a fixed memory mapping is used for the allocation pool --
note that we can't mmap an arbitrary chunk of memory, because the shadow memory hasn't been mapped yet
(for the reasons discussed in http://code.google.com/p/address-sanitizer/issues/detail?id=24, we cannot map the shadow earlier)

The patch drops the program startup time from several second to half a second,
which speeds up the execution of ASan tests noticeably.
Because of the virtual memory size occupied by the programs it's hard
to speed up the shutdown time, which would've also helped the tests.

Alexander Potapenko 553c208d22 This patch moves the code reading /proc/self/environ into AsanGetEnv
in asan_linux.cc, because /proc is unavailable on Mac.
Instead the Mac version of AsanGetEnv iterates over the array of
environment variables obtained from _NSGetEnviron()
