Change the LC_ID_DYLIB of ASan's dynamic libraries on OS X to be set to "@rpath/libclang_rt.asan_osx_dynamic.dylib" and similarly for iossim. Clang driver then sets the "-rpath" to be the real path to where clang currently has the dylib (because clang uses the relative path to its current executable). This means if you move the compiler or install the binary release, -fsanitize=address will link to the proper library.

Summary:
Appropriately set/clear the FeatureBit for Mips16 when these assembler directives are used and also emit ".set nomips16" (previously, only ".set mips16" was being emitted).
These improvements allow for better testing of the .cpload/.cprestore assembler directives (which are not supposed to work when Mips16 is enabled).
Test Plan: The test is bare-bones because there are no MC tests for Mips16 instructions (there's only one, which checks that the Mips16 ELF header flag gets set), and that suggests to me that it has not been implemented yet in the IAS.

When our RuntimeDebugBuilder calles fflush(NULL) to flush all output streams, it
is important that the types we use in the call match the ones used in a
declaration of fflush possible already available in the translation unit.
As we just pass on a NULL pointer, the type of the pointer value does not really
matter. However, as LLVM complains in case of mismatched types, we make sure
to create a NULL pointer of identical type.
No test case, as RuntimeDebugBuilder is not permanently used in Polly. Calls to
it are until now only used to add informative output during debugging sessions.

test/MC/ARM/directive-eabi_attribute.s was missing several tests of object file
encodings relative to the existing tests for assembly file encodings. This
commit adds the missing tests.

Summary:
Handle -extra-arg and -extra-arg-before options in the
CommonOptionsProvider so they can be used in all clang tools. Adjust arguments
in a CompilationDatabase wrapper instead of adding ArgumentsAdjuster to the
tool.

This is experimental, just barely enough to get things to not
immediately combust.
A note for those who are curious:
Only lld can successfully link the object files, other linkers truncate
the section names making the debug sections illegible to debuggers.
Even with this in mind, we believe we are having trouble with SECREL
relocations.

let's let lldb try the arch default unwind every time but not destructively --
it doesn't permanently replace the main unwind method for that function from
now on.
This fix is for <rdar://problem/18683658>.
I tested it against Ryan Brown's go program test case and also a
collection of core files of tricky unwind scenarios

The ELF writer creates a invalid binary for few cases with large filesize and
memory size for segments. This patch addresses the functionality and updates the
test. This patch also cleans up parts of the ELF writer for future enhancements

is "invalid" -- it is past the end of the stack trace. Add a new
method IsCompletedStackWalk() so we can tell if an invalid stack
frame is from a complete backtrace or if it might be worth re-trying
the last unwind with a different method.
This fixes the unwinder problems Ryan Brown was having with go
programs. The unwinder can (under the right circumstances) still
destructively replace unwind plans permanently - I'll work on
that in a different patch.
