Users of ARCH_ARM_* defines don't care about first vs. second arch,
set ARCH_ARM_* regardless of which arch is arm.

This is the first step to build 32-bit libraries in a 64-bit product.
It will work like this:
1) In the product's BoardConfig.mk, define:
TARGET_2ND_ARCH, TARGET_2ND_ARCH_VARIANT, TARGET_2ND_CPU_VARIANT.
The build system uses those variables to set up an additional compiler
environment for the second arch.
2) When parsing Android.mks, the build system sets up rules to build a
module for both the 1st arch and the 2nd arch, unless it's explicitly
asked to skip so.
Android.mk will be adapted if there is additional rule of generating
source files.
The build system will accept arch-specific LOCAL_ variables, such as
LOCAL_CFLAGS_arm, LOCAL_CFLAGS_armv7-a-neon, LOCAL_CFLAGS_cortex-a15,
LOCAL_CFLAGS_aarch64 etc. Modules use such variables to set up build for
various archs at the same time.
3) Install binary of the 2nd arch by adding "<module_name>:32" to
PRODUCT_PACKAGES. All 2nd-arch libraries linked in by "<module_name>:32"
will be installed automatically.

Conflicts:
core/combo/TARGET_linux-arm.mk
ARCH_X86_HAVE_MMX, ARCH_X86_HAVE_SSE, ARCH_X86_HAVE_SSE2,
and ARCH_X86_HAVE_SSE3 were all always on. There are no longer any makefiles
or code that are conditional on any of these, so let's just remove them
rather than encourage anyone to mess with knobs that don't work.

Currently, x86 target only has generic i686 and x86-atom
as arch variants. This patch adds the ability to have
more than two arch variants. Defining a new arch variant
is similiar to ARM targets, by adding a new file in
core/combo/arch/x86. These files also define what
capabilities the targeting CPU has (e.g. having SSE2,
SSE3, etc.).
We define arch variants for Sandy Bridge, Ivy Bridge,
Haswell; upcoming arches can be easily added to this
set with future patches.

For the current MIPS compiler __builtin___clear_cache() generates synci instruction only with -msynci option So, add -msynci to all mips32r2 makefiles. Also add msynci to the list flags not recognized by clang.

Everything that is based on ARMv7a should have a cp15 TLS register.
Enable it by default so it's not accidentally missed in newer board
configurations. In fact, this could be enabled for ARMv6 as well, but we
currently don't distinguish between ARMv5 and ARMv6 in the build system.
This can still be disabled by setting it to "false" in the board
configuration, but this shouldn't ever be needed.

This is the result of a recent conversation around the x86 ABI
and its relationship with how we build platform images. Briefly:
- We want to use feature-based macros like ARCH_X86_HAVE_$FEATURE
instead of relying on explicit compiler macros like -DUSE_$FEATURE
- We want to allow for other x86-based arch variants, e.g. if
someone wants to build Android for a CPU that doesn't support
the NDK x86 ABI. However, we need to ensure these are not
tagged compatible by mistake (see check at the end of TARGET_linux-x86.mk)
- There are several flags which use is dubious now that we have
a dedicated toolchain to build all the x86 stuff. Comment them
as 'to be considered for removal'. We'll do the proper checks
later.

This allows TARGET_ARCH_VARIANT to be set by the vendor before we choose the
architecture in core/combo/select.mk.
Also add a primitive armv7-a.mk for turning on hardware floating point.
