Atomic functions used in external/libcxx/include/atomic when compiled with Clang
will require intrinsic functions exist only for prescott or newer CPUs.

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.)

We no longer need gcc for host builds, since those all run through clang. This
header include, however, triggers errors about SSE intrinsics by replacing
the more relevant include dirs that we should be using.

Yikes. Don't know how this slipped through code review.
I had actually mentioned a need for cleanup in this part of the build
system earlier, since the amount of duplication between
transform-o-to-* for each arch means we might fix things incorrectly
in one of them (as I've just shown). Similarly, code reviewers are
likely to skim each one after the first if they all look close enough
(which is presumably what happened here).

It is libstdc++.so, after all, and the naming makes sense for the host
this way (since it also uses libstdc++).

On some Linux distributions (spotted here on OpenMandriva Lx, but I'm
pretty sure some others do the same thing), "which javac" returns
/usr/bin/javac, which is a symlink to "../../etc/alternatives/javac",
which in turn points at whatever the JDK the user picked as his default.
Given "../../etc/alternatives/javac" is a relative symlink, the next
iteration of LSLINE=$(ls -l "$JAVAC") fails (no ../../etc/alternatives/java
relative to the build directory), causing tools.jar not to be found.
Using realpath and readlink where possible should work in all cases.

LPAE indicates better instructions can be used when atomicity guarantees are
needed. However, LPAE's presence isn't advertised by clang/GCC. We fake an
ARM feature to advertise its presence on architectures where it is.
Also, add a TODO documenting that cortex-a15 is not the correct CPU variant
for krait.

The compiler run-time library should always be the _last_ thing linked
when building static executables. This was being done correctly for
libgcc, but not when using compiler-rt.

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

- Added LOCAL_DEX_PREOPT_FLAGS to pass extra flags to dex2oat.
- Added macro add-product-dex-preopt-module-config to specify almost
arbitrary dex-preopt config/flags to modules in product
configuration:
$(call \
add-product-dex-preopt-module-config,<module_name_list>,<config_or_flags>)
How <config_or_flags> is interpreted is decided by
dex_preopt_odex_install.mk and dex2oat. For now if it's "disable" we
disable dexpreopt for the given modules; otherwise pass it to dex2oat as
command line flags.
- If there are multiple configs for the same module in the product
inheritance, the first takes precedence.
- Added PRODUCT_DEX_PREOPT_DEFAULT_FLAGS so you can specify default
dex2oat flags in product configuration.
- Added PRODUCT_DEX_PREOPT_BOOT_FLAGS to specify flags of building boot.oat.

Because LOCAL_CXX_STL modifies a module's required shared libaries,
we need this for also prebuilt shared libraries and executables.

my_compiler_dependencies was never assigned to, but the way it was
included in the rules prevented the user from being able to use | in
LOCAL_ADDITIONAL_DEPENDENCIES. Since it is unneeded, just remove it.

Although only some of these flags will be used for some
targets or hosts, they must all be cleared to avoid carrying
over from one project to another.

Use a temporary variable my_checked_module instead,
so that we don't override the 2nd_arch's checked module with the
1st_arch's in multilib build.
Note that by default we checkbuild 2nd_arch only for host modules,
but not for target modules.
We enable multlib for target modules by default, it would take too
much time to checkbuild for both archs. For 32-bit modules actually we
can checkbuild a 32-bit product.

Target tests weren't approrpiately using the libc++ gtest for
libc++_static, and the hosts tests were still using the old check.

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).
