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.

On a default FreeBSD install Bash is not installed and fdescfs is not

We should check whether the compiler & linker support ARM64 before attempting
to build a version of compiler-rt for it. Otherwise things will go badly.

Makes sure ARM bots don't run AArch64 and vice-versa, since not all
AArch64 systems can run AArch32 and no ARM hardware can run AArch64.

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.

This is simply to help clarity of the code. The functions are built as thumb
only if Thumb2 is available (__ARM_ARCH_ISA_THUMB == 2). Sink the selection
into the location of the definition and make DEFINE_COMPILERRT_THUMB_FUNCTION
always define a thumb function while DEFINE_COMPILERRT_FUNCTION always selects
the default.
Since the .thumb_func directive is always available (at least on Linux, Windows,
and BSD), sinking the macro right into the macro works just as well.
No functional change intended.

The arm builtins converted into thumb in r213481 are not working
on darwin. On apple platforms, .thumb_func directive is required
to generated correct symbols for thumb functions.

Summary:
Changed cmake/config-ix.cmake to add support for different MIPS architectures: mips, mipsel, mips64, mips64el
In profile code there is no target based dependencies, so just enabling mips flag does the work.

Summary:
Fix the function that gets stack frame description by address in
thread stack, so that it clearly indicates failures. Make this error non-fatal,
and print as much information as we can in this case. Make all errors in
ParseFrameDescription non-fatal.

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.

* Detect Android toolchain target arch and set correct runtime library name.
* Merged a lot of Android and non-Android code paths.
* Android is only supported in standalone build of compiler-rt now.
* Linking lsan-common in ASan-Android (makes lsan annotations work).
* Relying on -fsanitize=address linker flag when building tests (again,
unification with non-Android path).
* Runtime library moved from lib/asan to lib/linux.

The ldrexd and strexd instructions are undefined for the ARMv7M
architecture, so we cannot use them to implement the
__sync_fetch_and_*_8 builtins. There is no other way to implement
these without OS support, so this patch #ifdef's these functions out
for M-class architectures.
There are no tests as I cannot find any existing tests for these
builtins.
I used the __ARM_ARCH_PROFILE predefine because __ARM_FEATURE_LDREX is
deprecated and not set by clang.

Changed files:
config-ix.cmake: Enabled UBSan for MIPS32
sanitizer_stacktrace.cc: Program counter for MIPS32 is four byte aligned

This patch is part of an effort to implement a more generic debugging API, as proposed in http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-July/074656.html, with first part reviewed at http://reviews.llvm.org/D4466. Now adding several new APIs: __asan_report_present, __asan_get_report_{pc,bp,sp,address,type,size,description}, __asan_locate_address. These return whether an asan report happened yet, the PC, BP, SP, address, access type (read/write), access size and bug description (e.g. "heap-use-after-free"), __asan_locate_address takes a pointer and tries to locate it, i.e. say whether it is a heap pointer, a global or a stack, or whether it's a pointer into the shadow memory. If global or stack, tries to also return the variable name, address and size. If heap, tries to return the chunk address and size. Generally these should serve as an alternative to "asan_describe_address", which only returns all the data in text form. Having an API to get these data could allow having debugging scripts/extensions that could show additional information about a variable/expression/pointer. Test cases in test/asan/TestCases/debug_locate.cc and test/asan/TestCasea/debug_report.cc.
