Evgenii Stepanov 6708b6c99c Fix AddressSanitizer link order and multilib setup.
ASan runtime library (when using dynamic linking) must be the first
dependency of the main executable to achieve correct symbol
interposition. This matches how the clang driver works.

In multilib setup, ASan-RT name depends on the target arch:
  /system/lib/libclang_rt.asan-arm-android.so
  /system/lib64/libclang_rt.asan-arm64-android.so

We also set RPATH to /system/lib/asan or /system/lib64/asan
to have a place for ASan-only versions of system libraries.

Stephen Hines 1568029218 Add more support for GLOBAL_CONLYFLAGS.
This will be necessary to support -std=gnu99 mode for clang 3.6, which
defaults to C11 mode (unlike prior releases that use C99).

Stephen Hines 039675adb8 Fix RS_TRIPLE and RS_TRIPLE_CFLAGS.
Bug: 17333374

Add RS_TRIPLE_CFLAGS to ensure that we build with the proper defines on
targets like x86. This also changes all build targets to use the
proper 32/64-bit triples when creating their runtime libraries.

Ying Wang 1f9828387d Refactor llvm_config.mk and support the 2nd arch
1. Following the setup of gcc in build/core/combo/,
we added the [HOST|TARGET]_<arch>.mk clang config files,
and load only the configs needed by the current product.
2. Added support for the 2nd arch.
