Clang 3.6 (including the snapshot present in AOSP) added support for
-mcpu=cortex-a15 -- there's no need to fall back to generic armv7-a
anymore.

http://llvm.org/bugs/show_bug.cgi?id=15086,
llvm tail call optimization is wrong for x86.
For Android/x86 to use SSE* instructions safely, stack should be 16-byte
aligned before JNI function call, which isn't true for all x86 device,
so -mstackrealign should be the default.

Pass -fsanitize=address instead of manually specifying asan libraries
and other linker flags.
Note that we enable LOCAL_ALLOW_UNDEFINED_SYMBOLS by default for host
builds because ASAN only links symbols in the final executable, so
there will _always_ be undefined symbols in intermediate libraries.

This change also defaults C compilations with clang to gnu99, and turns off
the -Winconsistent-missing-override flag, since we need further cleanup to
turn it on. -finline-functions is an unnecessary flag that only gcc needs.

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

Now that I checked in the latest prebuilts, clang will automatically use
color on terminals and no color on redirection to files or non-terminals.

Previously ccache is disabled when it fails calling clang's preprocessor with
unused arguments (such as '-Wa,--noexecstack') in the command line.
See http://petereisentraut.blogspot.com/2011/05/ccache-and-clang.html.
(-Qunused-arguments suppresses more than
-Wno-unused-command-line-argument does.)

For mips target, gcc passes -KPIC to assembler by default,
but clang passes -KPIC only if -fPIC or -fpic is given.

These aren't needed now that we only use the compiler/headers that exist in
the prebuilts/clang directory.

This removes the hard-coded '3.5' in the various paths and makes switching to
a new toolchain easier from the command line (m LLVM_PREBUILTS_VERSION=3.6).

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.
