Updates to Win64EH.h structures.
Change member types of RuntimeFunction and UnwindInfo from uint64_t to
uint32_t:
These members represent addresses. According to MSDN, they are image
relative, that is, they are 32-bit offsets from the starting address
of the image that contains the function table entry.
See MSDN for more information:
RUNTIME_FUNCTION: http://msdn.microsoft.com/en-us/library/ft9x1kdx.aspx
UNWIND_INFO: http://msdn.microsoft.com/en-us/library/ddssxxy8.aspx
Make Win64.h platform-neutral:
The standard types unit8_t, uint16_t and uint32_t are replaced with
their counterparts from Endian.h. Accessor functions are introduced to
replace bit fields.

docs: Sphinxify `docs/tutorial/`
Sorry for the massive commit, but I just wanted to knock this one down
and it is really straightforward.
There are still a couple trivial (i.e. not related to the content)
things left to fix:
- Use of raw HTML links where :doc:`...` and :ref:`...` could be used
instead. If you are a newbie and want to help fix this it would make
for some good bite-sized patches; more experienced developers should
be focusing on adding new content (to this tutorial or elsewhere, but
please _do not_ waste your time on formatting when there is such dire
need for documentation (see docs/SphinxQuickstartTemplate.rst to get
started writing)).
- Highlighting of the kaleidoscope code blocks (currently left as bare
`::`). I will be working on writing a custom Pygments highlighter for
this, mostly as training for maintaining the `llvm` code-block's lexer
in-tree. I want to do this because I am extremely unhappy with how it
just "gives up" on the slightest deviation from the expected syntax
and leaves the whole code-block un-highlighted.
More generally I am looking at writing some Sphinx extensions and
keeping them in-tree as well, to support common use cases that
currently have no good solution (like "monospace text inside a link").

This patch introduces initial-exec model support for thread-local storage
on 64-bit PowerPC ELF.
The patch includes code to handle external assembly and MC output with the
integrated assembler. It intentionally does not support the "old" JIT.
For the initial-exec TLS model, the ABI requires the following to calculate
the address of external thread-local variable x:
Code sequence Relocation Symbol
ld 9,x@got@tprel(2) R_PPC64_GOT_TPREL16_DS x
add 9,9,x@tls R_PPC64_TLS x
The register 9 is arbitrary here. The linker will replace x@got@tprel
with the offset relative to the thread pointer to the generated GOT
entry for symbol x. It will replace x@tls with the thread-pointer
register (13).
The two test cases verify correct assembly output and relocation output
as just described.
PowerPC-specific selection node variants are added for the two
instructions above: LD_GOT_TPREL and ADD_TLS. These are inserted
when an initial-exec global variable is encountered by
PPCTargetLowering::LowerGlobalTLSAddress(), and later lowered to
machine instructions LDgotTPREL and ADD8TLS. LDgotTPREL is a pseudo
that uses the same LDrs support added for medium code model's LDtocL,
with a different relocation type.
The rest of the processing is straightforward.
