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.

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.
