Richard Smith 3e284699d9 In C++, if we hit an error in the class-head, don't try to parse the class body.
Our error recovery path may have made the class anonymous, and that has a pretty
disastrous impact on any attempt to parse a class body containing constructors.

Andrew Trick 510e606e19 RegisterPressure API. Add support for physical register units.
At build-time register pressure was always computed in terms of
register units. But the compile-time API was expressed in terms of
register classes because it was intended for virtual registers (and
physical register units weren't yet used anywhere in codegen).

Now that the codegen uses physreg units consistently, prepare for
tracking register pressure also in terms of live units, not live
registers.

Richard Smith aebee680b6 Simplify slightly by seperating out the responsibility for emission of a caret
diagnostic from the emission of macro backtraces. Incidentally, we now get the
displayed source location for a diagnostic and the location for the caret from
the same place, rather than computing them separately. No functionality change.

Sean Silva d7fb396eb2 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").

DeLesley Hutchins 8edae13dd0 Thread safety analysis: Add a new "beta" warning flag: -Wthread-safety-beta.
As the analysis improves, it will continue to add new warnings that are
potentially disruptive to existing users.  From now on, such warnings will
first be introduced under the "beta" flag.  Such warnings are not turned on by
default; their purpose is to allow users to test their code against future
planned changes, before those changes are actually made.  After a suitable
migration period, beta warnings will be folded into the standard
-Wthread-safety.

Chandler Carruth 210c77b38c Add -whole-archive around the ASan runtime archive in the link command.
This ensures that even though it comes first, we pick up its .o files.
Note that if we can use this (or something similar / equivalent) on
other platforms, we could potentially remove
ReplaceOperatorsNewAndDelete from the ASan runtimes.

We should probably do something similar for TSan and MSan as well.

Shuxin Yang 73285933c9 For rdar://12329730, last piece.
This change attempts to simplify (X^Y) -> X or Y in the user's context if we know that
only bits from X or Y are demanded.

  A minimized case is provided bellow. This change will simplify "t>>16" into "var1 >>16".

  =============================================================
  unsigned foo (unsigned val1, unsigned val2) {
    unsigned t = val1 ^ 1234;
    return (t >> 16) | t; // NOTE: t is used more than once.
  }
  =============================================================

  Note that if the "t" were used only once, the expression would be finally optimized as well.
However, with with this change, the optimization will take place earlier.

  Reviewed by Nadav, Thanks a lot!
