Insert padding before the __cxa_exception header to ensure the thrown
object is sufficiently aligned.
r303175 annotated field unwindHeader of __cxa_exception with attribute
'aligned' to ensure the thrown object following the __cxa_exception
header was sufficiently aligned. This caused changes in the field
offsets of __cxa_exception relative to the start of the thrown object,
which was an ABI breaking change for some clients.
Instead of annotating field unwindHeader, this commit inserts extra
space before the header. This ensures the thrown object following the
header is sufficiently aligned without changing the field offsets, thus
avoiding any ABI breakages.

Fix ASAN build with older compiler-rt versions.
compiler-rt recently added the __asan_handle_no_return() function that libc++abi
needs to use, however older versions of compiler-rt don't declare this interface
publicly and that breaks the libc++abi build.
This patch attempts to fix the issues by declaring the asan function explicitly,
so we don't depend on compiler-rt to provide the declaration.

[libc++abi] Fix ASAN build with older compiler-rt versions.
Summary:
compiler-rt recently added the `__asan_handle_no_return()` function that libc++abi needs to use, however older versions of compiler-rt don't provide this interface and that breaks the libc++abi build.
This patch attempts to fix the issues by using a macro to detect if `asan_interface.h` is new enough to provide the function.

Reland "When built with ASan, __cxa_throw calls __asan_handle_no_return"
The ASan runtime on many systems intercepts cxa_throw just so it
can call asan_handle_no_return first. Some newer systems such as
Fuchsia don't use interceptors on standard library functions at all,
but instead use sanitizer-instrumented versions of the standard
libraries. When libc++abi is built with ASan, cxa_throw can just
call asan_handle_no_return itself so no interceptor is required.

Throwing an exception for the first time may lead to call calloc to
allocate memory for __cxa_eh_globals. If the memory pool is exhausted
at that moment, it results in abnormal termination of the program.
This patch addresses the issue by using fallback_malloc in that case.

Fix ARM __cxa_end_cleanup() and gc-sections.
This commit adds SHF_ALLOC and SHF_EXECINSTR section flags to
`.text.__cxa_end_cleanup` section. This fixes a link error when we are
using integrated-as and `ld.gold` (with `-Wl,--gc-sections` and
`-Wl,--fatal-warnings`.)
Detailed Explanation:
1. There might be some problem with LLVM integrated-as. It is not
emitting any section flags for text sections. (This will be fixed in
an independent commit.)
2. `ld.gold` will skip the external symbols in the section without
SHF_ALLOC. This is the reason why `.text.__cxa_end_cleanup_impl`
section is discarded even though it is referenced by
`__cxa_end_cleanup()`.
This commit workaround the problem by specifying the section flags
explicitly.

Add a descriptive name for a constant. Also I'm at least temporarily waging war on throw specs, both old and new style. Except where we have already publicly exposed the throw spec, I'm getting rid of them. They may come back later. But they seem somewhat prone to cyclic dependencies here. The throw spec implies compiler generated code that this library has to jump to during stack unwinding. I'd like to minimize the possiblity that the code used to properly make that jump is itself creating such jumps.

By changing all of the throw() specs to noexcept I've been able to compile and link all of the source files into a dylib. Prior to this substitution the changed functions were calling __cxa_call_unexpected which isn't implemented yet. However in none of these cases do we actaully want __cxa_call_unexpected to be called. Primative buildit script added.

Got fooled by fallback_malloc.cpp source file: it is really a private header. I've manually included it into the only place it is used: cxa_exception.cpp.

I kept getting confused among the __cxa_exception*, the _Unwind_Exception* and the void* to the thrown object. So I've gone through these two files and attempted to institute a consistent variable naming scheme, and in a few instances, turned void* into a concrete* to have the type system help me out. No change in functionality for this commit is intended.

Substituted std::get_terminate() for direct access to the handler function pointer (which is now a static in cxa_handlers.cpp). This has the advantage of going through the atomic API and so is less likely to cause a data race. Ditto for unexpected.
