abc91eacac Speculatively revert asan coverage changes 194702-194704. 
Apple's bootstrapped LTO builds have been failing, and these changes (along
with llvm 194701) are the only things on the blamelist.  I will either reapply
these changes or help debug the problem, depending on whether this fixes the
buildbots.

67a1eef05b tsan: remove __sanitizer_set_report_fd function from public interface 
__sanitizer_set_report_path now accepts two special values - stderr and stdout
logging to other file descriptors is not supported anymore,
it's fragile in presence of multiple processes, fork, etc

5cbab07d02 DataFlowSanitizer; compiler-rt changes. 
DataFlowSanitizer is a generalised dynamic data flow analysis.

Unlike other Sanitizer tools, this tool is not designed to detect a
specific class of bugs on its own.  Instead, it provides a generic
dynamic data flow analysis framework to be used by clients to help
detect application-specific issues within their own code.

fd61b6f0c8 [asan] make asan work with 7fff8000 offset and prelink 
When prelink is installed in the system, prelink-ed
libraries map between 0x003000000000 and 0x004000000000 thus occupying the shadow Gap,
so we need so split the address space even further, like this:
|| [0x10007fff8000, 0x7fffffffffff] || HighMem    ||
|| [0x02008fff7000, 0x10007fff7fff] || HighShadow ||
|| [0x004000000000, 0x02008fff6fff] || ShadowGap3 ||
|| [0x003000000000, 0x003fffffffff] || MidMem     ||
|| [0x00087fff8000, 0x002fffffffff] || ShadowGap2 ||
|| [0x00067fff8000, 0x00087fff7fff] || MidShadow  ||
|| [0x00008fff7000, 0x00067fff7fff] || ShadowGap  ||
|| [0x00007fff8000, 0x00008fff6fff] || LowShadow  ||
|| [0x000000000000, 0x00007fff7fff] || LowMem     ||

Do it only if necessary.

Also added a bit of profiling code to make sure that the
mapping code is efficient.

Added a lit test to simulate prelink-ed libraries.
Unfortunately, this test does not work with binutils-gold linker.
If gold is the default linker the test silently passes.

Also replaced
__has_feature(address_sanitizer)
with
__has_feature(address_sanitizer) || defined(__SANITIZE_ADDRESS__)
in two places.

Patch partially by Jakub Jelinek.
