[asan] asan_allocator2: do less work under the quarantine lock; make the strcasecmp test more resistant to the contents of unaddressable memory 

llvm-svn: 172048

Fixes using ubsan on shared libraries in linux, for example.

[asan] make the slow unwinder a bit more robust. The unittests pass with fast_unwind_on_fatal=0, but I still observe some differences between the two unwinders

[asan] add a new interface function __asan_describe_address, useful for running asan-ified binary under a debugger (e.g. gdb)

[asan] implement more strict checking for memset/etc parameters. Instead of checking the first and the last byte, we check the entire shadow region. This costs ~10 slowdown for the instrumented functions. Motivated by a nasty memset-buffer-overflow-by-140-bytes in chrome which was reported as a use-after-free or not at all

Define COMPILER_RT_CAN_EXECUTE_TESTS variable on platforms where we can produce working binaries and use it in build rules for sanitizers tests
