This reverts commit ab5265ebe6.
This broke the mips64 build (which, stupidly, I hadn't tested):
system/core/libpixelflinger/codeflinger/MIPS64Assembler.h:24:35: fatal error: tinyutils/KeyedVector.h: No such file or directory
#include "tinyutils/KeyedVector.h"

Added ARMtoMips64Assembler class that translates ARM instructions to MIPS64r6
instructions.
Added MIPS64r6 assembly implementations for col32cb16_blend and t32cb16_blend
functions.
Added MIPS32r2 assembly implementation for col32cb16_blend function.
Added tests for MIPS64r6 (assembler, disassembler and assembly implementation
functions).
Added MIPS32 tests for assembly implementation functions.
Minor bug fixes for MIPS32r2 branch.

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.

* Explicitly specify default .align 0.
* Use standard ldmfdlo instruction.
* Before and after gas outputs are identical,
with align 0 sections.
* Objdump showed .text/.data/.bss section alignment
attributes are 2^0 from gas and 2^2 from llvm
assembler. These .S files might be working when
compiled by gas, but llvm assembler's output should
be more correct or conservative.

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

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.

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.
