arm64: tishift: use asm EXPORT_SYMBOL()
For a while now it's been possible to use EXPORT_SYMBOL() in assembly files, which allows us to place exports immediately after assembly functions, as we do for C functions.
As a step towards removing arm64ksyms.c, let's move the tishift exports to the assembly file the functions are defined in.
There should be no functional change as a result of this patch.

Commit fb8722735f50 ("arm64: support __int128 on gcc 5+") added support for the __int128 data type, but this breaks the build in some configurations where GCC ends up emitting calls to the __lshrti3 helper in libgcc, which results in a link error:
kernel/sched/fair.o: In function `__calc_delta': fair.c:(.text+0xca0): undefined reference to `__lshrti3' kernel/time/timekeeping.o: In function `timekeeping_resume': timekeeping.c:(.text+0x3f60): undefined reference to `__lshrti3' make: *** [vmlinux] Error 1
Fix the build by providing an implementation of __lshrti3, like we do already for __ashlti3 and __ashrti3.

arm64: support __int128 on gcc 5+
Versions of gcc prior to gcc 5 emitted a __multi3 function call when dealing with TI types, resulting in failures when trying to link to libgcc, and more generally, bad performance. However, since gcc 5, the compiler supports actually emitting fast instructions, which means we can at long last enable this option and receive the speedups.
The gcc commit that added proper Aarch64 support is: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=d1ae7bb994f49316f6f63e6173f2931e837a351d This commit appears to be part of the gcc 5 release.
There are still a few instructions, __ashlti3 and __ashrti3, which require libgcc, which is fine. Rather than linking to libgcc, we simply provide them ourselves, since they're not that complicated.

arm64: support __int128 on gcc 5+ Versions of gcc prior to gcc 5 emitted a __multi3 function call when dealing with TI types, resulting in failures when trying to link to libgcc, and more generally, bad performance. However, since gcc 5, the compiler supports actually emitting fast instructions, which means we can at long last enable this option and receive the speedups. The gcc commit that added proper Aarch64 support is: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=d1ae7bb994f49316f6f63e6173f2931e837a351d This commit appears to be part of the gcc 5 release. There are still a few instructions, __ashlti3 and __ashrti3, which require libgcc, which is fine. Rather than linking to libgcc, we simply provide them ourselves, since they're not that complicated.
