7428539a1c AArch64: enable MCJIT and tests now that everything passes.
This removes dire warnings about AArch64 being unsupported and enables
the tests when appropriate on this platform.

dfe076af98 Fix formatting in AArch64 backend.
This should fix three purely whitespace issues:
    + 80 column violations.
    + Tab characters.
    + TableGen brace placement.

No functional changes.

72062f5744 Add AArch64 as an experimental target.
This patch adds support for AArch64 (ARM's 64-bit architecture) to
LLVM in the "experimental" category. Currently, it won't be built
unless requested explicitly.

This initial commit should have support for:
    + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions
      (except the late addition CRC instructions).
    + CodeGen features required for C++03 and C99.
    + Compilation for the "small" memory model: code+static data <
      4GB.
    + Absolute and position-independent code.
    + GNU-style (i.e. "__thread") TLS.
    + Debugging information.

The principal omission, currently, is performance tuning.

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.
