The test refers to user_regs_struct.rip so it can only ever have worked
on x86-64. Put this code inside an appropriate #if, and add a similar
case for PowerPC64. (If we do likewise for ARM we can probably remove
the XFAILs, but I have no way of testing that.)
Those changes are enough to get the test working for me on big-endian
PowerPC64 Fedora 19.

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.

This commit changes the place where TSan runtime turns full path
to binary or shared library into its basename
(/usr/foo/mybinary -> mybinary). Instead of doing it as early as possible
(when we obtained the full path from the symbolizer), we now do it as
late as possible (right before printing the error report).
This seems like a right thing to do - stripping to basename is a detail
of report formatting implementation, and should belong there. Also, we
might need the full path at some point - for example, to match the
suppressions.

ParamTLS (shadow for function arguments) is of limited size. This change
makes all arguments that do not fit unpoisoned, and avoids writing
past the end of a TLS buffer.

When compiling with -mfpu=vfpv3, those tests began to pass, like the others
with "Illegal Instruction" error, so removing the XFAIL from them should
get the bot green (and have more tests!).

The current handling (manual execution of atexit callbacks)
is overly complex and leads to constant problems due to mutual ordering of callbacks.
Instead simply wrap callbacks into our wrapper to establish
the necessary synchronization.

This change adds UBSan check to upcasts. Namely, when we
perform derived-to-base conversion, we:
1) check that the pointer-to-derived has suitable alignment
and underlying storage, if this pointer is non-null.
2) if vptr-sanitizer is enabled, and we perform conversion to
virtual base, we check that pointer-to-derived has a matching vptr.

to pass in an opt build.
The test case in question does show UBSan catching the error, but it
doesn't then successfully set the exit code of the program. I'll let the
UBSan folks sort out why. It should reproduce trivially with an
optimized build.

ASAN, UBSAN and profile tests that don't work with arm-linux-gnueabi and
android also don't work on armv7l-linux-gnueabihf. Some of the tests have
known causes, others not yet. In order to get a green bot, I'm disabling
those tests for now and will investigate when the priority rises.

FreeBSD does not have libdl, so set it via lit.cfg instead of the test
input, as with asan. Also remove it from Darwin test runs - it's not
necessary, but harmless there.
Add FreeBSD to the list of hosts to test.

There is some strange interaction between mmap limit and unlimited stack
(ulimit -s unlimited), which results in this test failing when run with
"make".

This is needed so we can produce -i686- named libraries for
x86 Android (which is i686-linux-android).
An alternative solution would be keeping the "i386" name internally and
tweaking the OUTPUT_NAME of compiler-rt libraries.

The optimization for -gmlt/-gline-tables-only introduced in r218129 happened to break on Darwin and produce no line number information due to
an incompatibility with dsymutil. ASan tests have been failing because of that and we disabled the use of -gmlt for the tests in r218545. This patch re-enables the use of -gmlt, because we have conditionally disabled the incompatible optimization in LLVM, so -gmlt now works on Darwin. Once Darwin's dsymutil is modified to allow this optimization, we can re-enable the optimization in LLVM.
