DW_TAG_atomic_type was already included in Dwarf.defs and emitted correctly,
however Verifier didn't recognize it as valid.
Thus we introduce the following changes:
* Make DW_TAG_atomic_type valid tag for IR and DWARF (enabled only with -gdwarf-5)
* Add it to related docs
* Add DebugInfo tests

only in case when it was forced by C++11 'alignas', C11 '_Alignas'
or compiler attribute '__attribute__((aligned (N)))'.
* Emit DW_AT_alignment if alignment is specified for type/object.

This patch updates some of the existing Error examples, expands on the
documentation for handleErrors, and includes new sections that cover
a number of helpful utilities and common error usage idioms.

Summary:
The RFC proposal sent to increase the minimum required GCC version
to 4.8 received a lot of support. See the following thread:
http://lists.llvm.org/pipermail/llvm-dev/2016-October/105955.html,
This patch implements that by updating the docs. I believe the
references to libstdc++ 4.7 issues can be removed as well, please
let me know if that is not the case or if they should be updated
a different way.

Uses of this have all been updated to use LLVM_NODISCARD, which
matches the C++17 [[nodiscard]] semantics rather than those of GCC's
__attribute__((warn_unused_result)).

Summary:
* Describe new (3.3) parameter attribute group encoding, leaving old encoding there with a note about legacy
* Bring TYPE_BLOCK docs up to date
* Remove docs about obsolete (pre 3.0) TYPE_SYMTAB_BLOCK, TST_CODE_ENTRY
* Fix a couple of incorrect comments and remove one unused enum definition along the way

Added relocation names:
- R_AMDGPU_GOTPCREL32_LO
- R_AMDGPU_GOTPCREL32_HI
- R_AMDGPU_REL32_LO
- R_AMDGPU_REL32_HI
AMDGPU isa only supports 32-bit immediates. In order to access 64-bit address we need to generate 32-bit lo/hi relocations, and do the right math (separate patch). Currently we only generate one 32 bit relocation for lower bits for each access, losing higher bits. Hence we need relocations listed above.

This document describes the proposal to move to GitHub, and
compare the two proposals through various workflow examples,
presenting the current set of commands following by the ones
involved in each of the two proposals.
It is intended to supersede the previous "submodule proposal"
document entirely, and drive the discussion at the BoF during
the next Dev Meeting.

The core of the change is supposed to be NFC, however it also fixes
what I believe was an undefined behavior when calling:
va_start(ValueArgs, Desc);
with Desc being a StringRef.

Summary:
The acronym PR could be ambiguous to some users, especially those who
are used to interpreting it as GitHub's "pull request".

Support overriding the Doxygen & OCamldoc install directories,
and provide a more FHS-compliant defaults for both of them. This extends
r282240 that added this override for Sphinx-built documentation.
LLVM_INSTALL_DOXYGEN_HTML_DIR and LLVM_INSTALL_OCAMLDOC_HTML_DIR are
added, to control the location where Doxygen-generated and
OCamldoc-generated HTML docs are installed appropriately. They both
specify CMake-style install paths, and therefore can either by relative
to the install prefix or absolute.
The new defaults are subdirectories of share/doc/llvm, and replace
the previous directories of 'docs/html' and 'docs/ocaml/html' that
resulted in creating invalid '/usr/docs' that furthermore lacked proper
namespacing for the LLVM package. The new defaults are consistent with
the ones used for Sphinx HTML documentation, differing only in the last
component. Since the 'html' subdirectory is already used for Sphinx
docs, the 'doxygen-html' and 'ocaml-html' directories are used instead.

This patch updates WritingAnLLVMPass.rst to make it in line with current state of things.
Specifically:
* Makefile instructions replaced with CMake ones
* Filenames replaced with correct ones
* Example reformatted a bit to make it less confusing and more conforming to LLVM Coding Standards
* opt tool output updated with what it actually prints nowdays
* "gcse" (which doesn't exist anymore) replaced with "gvn" (which still does)
