[AArch64] This is a work in progress to provide a machine description
for the Cortex-A53 subtarget in the AArch64 backend.

This patch lays the ground work to annotate each AArch64 instruction
(no NEON yet) with a list of SchedReadWrite types. The patch also
provides the Cortex-A53 processor resources, maps those the the default
SchedReadWrites, and provides basic latency. NEON support will be added
in a subsequent patch with proper forwarding logic.

Verification was done by setting the pre-RA scheduler to linearize to
better gauge the effect of the MIScheduler. Even without modeling the
forward logic, the results show a modest improvement for Cortex-A53.

MC: Fix Intel assembly parser for [global + offset]

We were dropping the displacement on the floor if we also had some
immediate offset.

llvm-objdump: Print x64 unwind info in executable.

The original code does not work correctly on executable files because the
code is written in such a way that only object files are assumed to be given
to llvm-objdump.

Contents of RuntimeFunction are different between executables and objects. In
executables, fields in RuntimeFunction have actual addresses to unwind info
structures. On the other hand, in object files, the fields have zero value,
but instead there are relocations pointing to the fields, so that Linker will
fill them at link-time.

So, when we are reading an object file, we need to use relocation info to
find the location of unwind info. When executable, we should just look at the
values in RuntimeFunction.

[cleanup] Tidy up and modernize comments and the definition order for
the Use class.

More cleanups to come here. This class just needs some TLC.

[cleanup] Run clang-format over the Use code. It was *really*
inconsistent both with itself and with LLVM at large with formatting.
The *s were on the wrong side, the indent was off, etc etc. This is much
cleaner.

Also, go clang-format laying out the array of tags in nice columns.

[cleanup] Add a getOperandNo method to the Use class and implement it
out-of-line so that it can refer to the methods on User. As
a consequence, this removes the need to define one template method if
value_use_iterator in the extremely strange User.h header (!!!).

This makse Use.h slightly less peculiar. The only remaining real
peculiarity is the definition of Use::set in Value.h
