Evgeniy Stepanov f62cd5559e [asan] Fix malloc interception on Android L Preview.
Format of __libc_malloc_dispatch has changed in Android L.
While we are moving towards a solution that does not depend on bionic
internals, here is something to support both K* and L releases.

Evgeniy Stepanov 465466e80c [msan] Stop demangling function name in the stack origin report.

Alexey Samsonov 15c9669615 [ASan] Collect unmangled names of global variables in Clang to print them in error reports.
Currently ASan instrumentation pass creates a string with global name
for each instrumented global (to include global names in the error report). Global
name is already mangled at this point, and we may not be able to demangle it
at runtime (e.g. there is no __cxa_demangle on Android).

Instead, create a string with fully qualified global name in Clang, and pass it
to ASan instrumentation pass in llvm.asan.globals metadata. If there is no metadata
for some global, ASan will use the original algorithm.

This fixes https://code.google.com/p/address-sanitizer/issues/detail?id=264.

Evgeniy Stepanov db298121e0 [msan] Use real memset/memcpy/memmove in interceptors.
Our versions are not exactly as fast as libc's, and
MSan uses them heavily (even compared to other sanitizers).

This will break if libc version of mem* are instrumented,
but they never are, and if they are, we should be able
to fix it on libc side.

Tim Northover 9775cffe14 MachO: add dummy armv6m architecture directory so clang_macho_embedded builds things.
Without some mention of armv6m in a subdirectory of builtins, the make code
doesn't even know that armv6m exists and is something it should be looking for
in the platform-specific Makefiles. This means that none of the functions
listed actually get built and we end up with an almost entirely empty
libclang_rt.a for armv6m.

Unfortunately, the assembly code in the usual arm directory has no hope of
running on armv6m, which only supports Thumb-1 (not even ARM mode), so adding
it there won't work. Realistically, we probably *will* want to put any
optimised versions in a separate directory, so creating it now is harmless.
