ed45970ac5 Add cfi directives to all arm assembly.
Since the ENTRY/END macros now have .cfi_startproc/.cfi_endproc, most of the
custom arm assembly has no unwind information. Adding the proper cfi directives
for these and removing the arm directives.

Update the gensyscalls.py script to add these cfi directives for the generated
assembly. Also fix the references to non-uapi headers to the proper uapi
header.

In addition, remove the kill.S, tkill.S, tgkill.S for arm since they are not
needed at all. The unwinder (libunwind) is able to properly unwind using the
normal abort.

After this change, I can unwind through the system calls again.

7f8863dc07 AArch64: Autogenerated syscalls for AArch64
This patch adds AArch64 syscalls, autogenerated using:
        ./libc/tools/gensyscalls.py

103ccde8fe Sort the syscalls.mk files, give all generated files the same header.
No non-comment changes to the .S files.

e4ffd9f234 Regenerate the system call stubs (to get x86_64).
This touches the x86 stubs too because arm, x86, and x86_64 now
all share the same header (at a source level), which causes a
reordering of the #include lines.

5c2772f59d The SYS_ constants should cover all __NR_ values.
<sys/linux-syscalls.h> only contains constants for the syscalls
we're generating stubs for. We want all the syscalls available
on the architecture in question.

Keep using <sys/linux-syscalls.h> on ARM for now because the
__NR_ARM_set_tls and __NR_ARM_cacheflush values aren't in <asm/unistd.h>.

9724ce3a09 Don't #define SYS_ constants unless they make sense for the current architecture.
Fixes the MIPS and x86 builds. strace tests whether syscalls
are supported using #ifdef of the appropriate SYS_ constant.

8ecf225827 Provide glibc-compatible SYS_* aliases for the __NR_* constants.
This helps us remove another external/strace bionic hack.
