As requested in the bug. This also rips __memcpy_chk out of memcpy.S,
which lets us cut down on copypasta (all of the implementations look
identical).

Test: mma on aosp_{arm,arm64,mips,x86,x86_64} internal master;
checkbuild on bullhead internal master; CtsBionicTestCases on bullhead.
No new failures.

There are a few instructions deprecated on armv8 that result in lots
of warnings. Add an arch directive so that these warnings go away.
This doesn't cause any problems because the instructions still
execute properly.
Bug: 38319728
Test: Built all of these assembler files and verified the warning are gone.

I accidentally broken the cortex-a53 because it directly includes files
from cortex-a15. Rather than revert that part, just copy over the files
that are needed directly so we don't run into this in the future.
Test: Built the aosp_angler-userdebug target using cortex-a53 as the
Test: arm target. Then built the bionic unit tests and ran them on
Test: an angler.

These directories all have Android.bp files that are always used now,
delete the Android.mk files.

This moves the generic arm/arm64/x86 settings into the main makefiles
and makes the rest of them derivatives. This better aligns with how
soong handles arch/cpu variants.
Also updates the Android.bp to make it consistent with the make
versions.

Add an optimized memset that is ~20% faster for cortex-a7 and
cortex-a53.
Add a 32 bit optimized cortex-a53 memcpy that is about ~20% faster
on cached data.
Fix the cortex-a15 __str{cat,cpy}_chk.S, memcpy_base.S to remove
the phony functions, since they aren't needed any more. Then add
a direct include of these for cortex-a53.
Verified the new functions by stepping through all of the major
paths and verifying the backtrace is still correct.
