docs: Convert ReleaseNotes to reST.
...
This is the last of the "regular" documents to convert to reST, and so
I'm declaring the initial clang reST conversion "done".
However,
- There are some documents in clang/www/ which probably should
be migrated into clang/docs/, such as www/OpenProjects.html
The primary thing blocking me from doing this right now is not knowing
how to set up a redirect so that the old URL's continue to work.
- LibASTMatchersReference.html is not reST. This page is auto-generated
by clang/docs/tools/dump_ast_matchers.py from the source and has some
collapse/expand logic that isn't expressible directly with Sphinx, so
just converting it to reST is not really a good strategy.
Manuel Klimek and I discussed this and the general agreed-upon
direction is making that page data-driven so that it, say, pulls in an
auto-generated blob of JSON which describes the matchers and builds up
the "matcher reference" part of the page with a small amount of JS.
- There are some rogue .txt files hanging around.
Also, I dropped the little dragon logo at the top because Sphinx was
warning about an external image reference (not sure why, but meh, I
didn't want to fight it). If anything, we would want such a logo
integrated into the site's overall theme, rather than hardcoded here.

...
The only way to read the eflags is using push and pop. If we don't
adjust the stack then we run over the first frame index. This is
not something that we want to do, so we have to make sure that
our machine function does not copy the flags. If it does then
we have to emit the prolog that adjusts the stack.
