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.

Add the missing AEABI functions that are part of the base platform ABI
specification. The provided implementation does the bare minimum to avoid
requiring libc headers. This permits the use of compiler-rt on bare-metal
environments which conform to EABI.

The architecture specific implementation of routines would be built and included
along with the generic implementation. This would result in multiple
definitions of those symbols.
The linker is free to select either of the two. Most of the time, this
shouldn't be too terrible as the forward iteration should catch the architecture
version due to the ordering. Rather than relying on the linker and build
infrastructure ordering things in a specific manner, only provide the
architecture version when available.
This reduces the size of compiler-rt, simplifies inspection of the library
implementations, and guarantees that the desired version is selected at a
slightly complex build system.

Re-apply SVN r213684 which was reverted in SVN r213724 since it broke the
build bots. Add a tweak to enable inclusion of the assembly sources in
standalone build as well.
Original commit message:
This patch address the PR20360. The CMake assembler build system
ignores the .S assembly files in builtins library build. This patch
fixes the issue.

Call it "libclang_rt.builtins-<arch>.a" to be consistent
with sanitizers/profile libraries naming. Modify Makefile
and CMake build systems and Clang driver accordingly.
Fixes PR19822.

Soon there will be an option to build compiler-rt parts as shared libraries
on Linux. Extracted from http://llvm-reviews.chandlerc.com/D3042

Since these are primarily useful for deeply embedded targets where code size is
very important, they are each in a separate file making use of infrastructure
in sync-ops.h. This allows a linker to include just the functions that are
actually used.
