There is clearly still plenty of simplification than can be done here by
using standard type traits instead of rolling our own in many places.

on the fact that we now build in C++11 mode with modern compilers. This
should flush out any issues. If the build bots are happy with this, I'll
GC all the code for coping without R-value references.

lib/Support/RWMutex.cpp contains an implementation of RWMutex that
uses pthread_rwlock, but when pthread_rwlock is not available (such as
under NaCl, when using newlib), it silently falls back to using the
no-op definition in lib/Support/Unix/RWMutex.inc, which is not
thread-safe.

Fix this case to be thread-safe by using a normal mutex.

baseline is now C++11, and we unconditionally add -std=c++11 to the
flags.

This has the dim potential to break some non-GNU-compatible compiler (in
terms of -std flags) using the makefiles, but those makefiles are
littered with GNU-style compile flags so it would be very surprising to
me for it to actually happen in practice. As always, do let me know if
there is a toolchain you're using where this doesn't work, and I'll be
watching the bots.

C++11. I'm not sure that this is a good idea, but I know some crazy
folks on the core working group who like to live dangerously, and they
should still be able to build LLD. =D

The switch has been thrown. While I'm still watching for any failures or
problems with this, the documentation can go ahead and move forward.

[Sparc] Emit 'restore' instead of 'restore %g0, %g0, %g0'. This improves the readability of the generated code.

When lowering a bitfield, CGRecordLowering would assign the wrong 
storage type to a bitfield in some cases and trigger an assertion.  In 
these cases the layout was still correct, just the bitfield info was 
wrong.

it, importers of B should not see the macro. This is complicated by the fact
that A's macro could also be visible through a different path. The rules (as
hashed out on cfe-commits) are included as a documentation update in this
change.

With this, the number of regressions in libc++'s testsuite when modules are
enabled drops from 47 to 7. Those remaining 7 are also macro-related, and are
due to remaining bugs in this change (in particular, the handling of submodules
is imperfect).

This documents some of the status of supported functionality in MSVC
quirks mode.  Some of this should be in
http://clang.llvm.org/compatibility.html instead when things have
stabilized.

Inside iterate, we scan backwards then scan forwards in a loop. When iteration
is not zero, the last node was just updated so we can skip it. But when
iteration is zero, we can't skip the last node.

For the testing case, fixing this will save a spill and move register copies
from hot path to cold path.
