Add support for AArch64 target. In cooperation with the LLVM patch, this should implement all scalar front-end parts of the C and C++ ABIs for AArch64. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. llvm-svn: 174055

[Driver] Default Generic_GCC aarch64 to -fasynchronous-unwind-tables In GCC, `aarch64-*-linux` and `aarch64-*-freebsd` made the switch in 2018 (https://gcc.gnu.org/pipermail/gcc-patches/2018-March/495549.html). In Clang, FreeBSD/Fuchsia/NetBSD/MinGW aarch64 default to -fasynchronous-unwind-tables. This patch defaults Generic_GCC aarch64 (which affects Linux) to use -fasynchronous-unwind-tables.

// The AArch64 PCS states that chars should be unsigned.
// CHECK: fno-signed-char
[AArch64][Clang][Linux] Enable out-of-line atomics by default. Generate outline atomics if compiling for armv8-a non-LSE AArch64 Linux (including Android) targets to use LSE instructions, if they are available, at runtime. Library support is checked by clang driver which doesn't enable outline atomics if no proper libraries (libgcc >= 9.3.1 or compiler-rt) found. Differential Revision: https://reviews.llvm.org/D93585
