This contains just enough for lib/Target/RISCV to compile. Notably a basic 
RISCVTargetMachine and RISCVTargetInfo. At this point you can attempt llc 
-march=riscv32 myinput.ll and will find it fails due to the lack of 
MCAsmInfo.

It seems the ARMv8 instruction set overview is no longer provided by ARM, so
I've removed it. Since most of the other documents were the same I unified the
two sections.

There's a more comprehensive ACLE and a real v8 ARM ARM now.

Build attribute sections can now be read if they exist via ELFObjectFile, and
the llvm-readobj tool has been extended with an option to dump this information
if requested. Regression tests are also included which exercise these features.

Also update the docs with a fixed ARM ABI link and a new link to the Addenda
which provides the build attributes specification.

Summary: This is the beginning of user documentation for the NVPTX back-end.  I want to ensure I am integrating this properly into the rest of the LLVM documentation.

In the spirit of r172109. Version control keeps a far more detailed
record of authorship anyways.

This updates the current references to links that work for me.
In the future, we should update the list of references itself to provide
information on newer architecture variants.

Thanks to Sean Silva for pointing out that the current links were broken!

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.

Before we learned about :doc:, we used :ref: and put a dummy link at the
top of each page. Don't do that anymore.

This fixes PR14891 as a special case.

Replaces old Pentium 4 documentation link with generic current documentation link.
