Tim Northover 25e8a6754e AArch64/ARM64: update Clang after AArch64 removal. 
A few (mostly CodeGen) parts of Clang were tightly coupled to the
AArch64 backend. Now that it's gone, they will not even compile.

I've also deduplicated RUN lines in many of the AArch64 tests. This
might improve "make check-all" time noticably: some of those NEON
tests were monsters.

James Molloy 8bdd24b1a9 [ARM64] Change inline assembly constraints to be more lax, to match the behaviour of Clang/AArch64 and GCC. 
GCC allows sub-64bit values to use the 'r' register constraint.

Tim Northover 9bb857a4f1 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.
