random_device::random_device(const string&) wrongly assumes that open
can only validly return a file descriptor greater than zero.

This results in random_device believing that it didn't successfully open
the device causing it to throw in it's constructor, this ends up leaking
a file descriptor.

The fix is simple, don't error on file descriptors which are zero.

The only remaining user didn't actually use the non-dynamic storage facility
this class provides.

The std::string is transitional and likely to be StringRefized shortly.

Layout-before edges are no longer used for layout, but they are
still there for dead-stripping. If we would just remove them
from code, LLD would wrongly remove live atoms that were
referenced by layout-befores.

This patch fixes the issue. Before dead-stripping, it scans all
atoms to construct a reverse map for layout-after edges. Dead-
stripping pass uses the map to traverse the graph.

No longer need to set ANDROID if COMPILER_RT_TEST_TARGET_TRIPLE is

No need to set ANDROID_COMMON_FLAGS.  These flags are already in

The code was actually correct. Sorry for the confusion. I have expanded the

Summary:
No filters should affect the display of errors. Fixed a few tests,
which had compile errors.

We need to think what we should do with mapped errors (-Werror).

Summary:
This seems like a more appropriate reaction to the user specifying a

Instrumentation passes now use attributes
address_safety/thread_safety/memory_safety which are added by Clang frontend.
Clang parses the blacklist file and adds the attributes accordingly.

Currently blacklist is still used in ASan module pass to disable instrumentation
for certain global variables. We should fix this as well by collecting the
set of globals we're going to instrument in Clang and passing it to ASan
in metadata (as we already do for dynamically-initialized globals and init-order
checking).

This change also removes -tsan-blacklist and -msan-blacklist LLVM commandline
flags in favor of -fsanitize-blacklist= Clang flag.
