[PATCH 0/3] Rust enablement for AArch64

[Jamie Cunliffe]

The first patch is from Miguel's tree to enable Rust support for
AArch64. This has been tested with the Rust samples, and the generated
code has also been manually inspected.

The second patch enables the PAC ret and BTI options in the Rust build
flags to match the options that are used when building C.

The third patch disables the neon and fp target features to avoid fp &
simd registers. The use of fp-armv8 will cause a warning from rustc
about an unknown feature that is specified. The target feature is
still passed through to LLVM, this behaviour is documented as part of
the warning. This will be fixed in a future version of the rustc
toolchain. This pull request should address it,
