Use external/safe-iop to check for overflows on arithmetic
operations.
Also remove an unnecessary copy of Vector/SharedBuffer from
codeflinger and use the copy from libutils instead.
Note that some of the unit tests are somewhat useless due to
test-runner limitations : gtest's ability to filter on abort message
doesn't work when combined with messages formatted by android's logging
system.

pixelflinger should not be used for new projects and should be moved out
of system/core at some point. As the first step, move all its headers
under system/core/libpixelflinger/include and update its Android.mk
files so they're not referring to the absolute system/core path anymore.

libagl is now the only remaining pixelflinger client in the Android
tree, and it links with pixelflinger dynamically.

Intel accidentally made this dead code in 2010 with commit
2bef93cc20, and no one's ever noticed.
Since no one noticing for so long implies that it doesn't matter,
let's just kill the supposedly optimized code.

Use expected inline behavior with clang.
GCC defaults to -std=gnu90, giving C89 inline semantics with GNU
extensions. Clang defaults to C99. Explicitly use gnu90.
Mark an unused parameter as __unused.
Fix some incorrect casts.

CodeCache casts base address to long and then adds size (of type
ssize_t) to get end address. This can cause sign-extension problems.
This patch instead uses simple pointer arithmetic.

For now, use generic C code instead of generated mips instructions,
in the same manner as used on x86 and x86_64 targets.

ARCH_ARM_HAVE_NEON is only ever defined to true, so test for that.
For the NEON function to be used, the file has to include
machine/cpu-features.h so that __ARM_HAVE_NEON is defined.

The error condition was not correctly detected: an error was
reported by checking that the index returned by CodeCache::cache
was non-zero. This did not work because this function can return
a positive value on success.

cacheflush doesn't exist on LP64 any more, and gcc's
__builtin___clear_cache is better in every way. Use it instead.

See the comment-block at the top of Aarch64Assembler.cpp
for overview on how AArch64 support has been implemented
In addition, this commit contains
[x] AArch64 inline asm versions of gglmul series of
functions and a new unit test bench to test the
functions
[x] Assembly implementations of scanline_col32cb16blend
and scanline_t32cb16blend for AArch64, with unit
test bench

GGLAssembler assumes addresses to be 32-bit and uses ARM 32-bit
instructions to load/store/manipulate addresses. To support, 64-bit
architectures, following changes has been done
1. ARMAssemblerInterface has been extended to support four new
operations ADDR_LDR, ADDR_STR, ADDR_SUB, ADDR_ADD. Base class
implements these virtual functions to use 32bit equivalent
function. This avoids existing 32-bit Assembler backend
implementations like ARMAssembler and MIPSAssembler from
mapping the new functions to existing equivalent routines.
This also allows 64-bit Architectures like AArch64 to override
the function in their assembler backend implementations.
2. GGLAssembler code (spread over GGLAssembler.cpp, GGLAssembler.h
and texturing.cpp) has been changed to use the new operations
for address operations.

Pixelflinger's code makes assumptions, at certain places,
that pointers can be stored as ints. This patch makes use
of uintptr_t wherever pointers are stored as int or cast
to int.

This patch adds a dozen more "shortcut" scanline-processing functions
to pixel-flingers. All of them avoid using the JIT for the corresponding
operation (on ARM), or using the generic and _extremely_ slow 'scanline'
function (on x86, where there is no JIT).
The shortcuts were selected by running the system under emulation
(build full_x86-eng, then launch emulator-x86), and correspond to
operations that are in use when using the system's typical UI features.
This makes it much more responsive and amenable to testing most
applications, at least those that don't use OpenGL ES heavily.
Note that HW OpenGLES emulation is under completion and should solve this
problem entirely, though is not there yet.
