* minimise flags duplication
* distingush between VISIBILITY C and CXX flags
* set only required flags - C and/or CXX

Nearly everything within the three Makefile.am's is identical.
Let's simplify things a little.

The adreno a3xx GPU is found in newer snapdragon devices, such as the
nexus4. The a3xx is GLESv3 and OpenCL capable, although that is not
enabled yet in gallium.
Compared to a2xx, it introduces an entirely new unified shader ISA, and
re-shuffles all or nearly all of the registers. The good news is that
(for the most part) the registers are more orthogonal, not combining
unrelated state in a single register. And that there is a lot more
flexibility, so we don't need to patch and re-emit the shader like we
did on a2xx.
The shader compiler is currently quite dumb, there would be a lot of
room for improvement with an optimizing pass. Despite that, with the
a320 in my nexus4 it seems to be ~2-3x faster compared to the a220 in my
HP touchpad.

Split the parts that are specific to adreno a2xx series GPUs from the
parts that will be in common with a3xx, so that a3xx support can be
added more cleanly.

There will be a new IR for a3xx, which has a very different shader ISA
(more scalar oriented). So rename to avoid conflicts later when I start
adding a3xx support to the gallium driver.

Currently works on a220. Others in the a2xx family look pretty similar
and should be pretty straightforward to support with the same driver.
The a3xx has a new shader ISA, and while many registers appear similar,
the register addresses have been completely shuffled around. I am not
sure yet whether it is best to support with the same driver, but
different compiler, or whether it should be split into a different
driver.
v1: original
v2: build file updates from review comments, and remove GPL licensed
header files from msm kernel
v3: smarter temp/pred register assignment, fix clear and depth/stencil
format issues, resource_transfer fixes, scissor fixes
