Alexander Potapenko 3825e9770b Minor fixes of the AsanProcMaps code on Mac: 
-- make the load command scan linear (instead of quadratic)
 -- do not create a nested AsanProcMaps instance for each address lookup

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 9301db4baa Add __asan_mach_override_ptr_custom, which allows to inject a custom memory allocator into mach_override_ptr().

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()
