about a few constructs in C++11 that are worth starting off in
a consistent manner within the codebase.
This will be matched with a change to clang-format's LLVM style which
will switch the options to support C++11 and use these conventions.

The feature was previously guarded with KMP_OS_LINUX || KMP_OS_WINDOWS but can
now be enabled/disabled independently to simplify porting.
Completes the work started in r202478.

it interoperate (minimally) with std::unique_ptr<T>. This is part of my
plan to migrate LLVM to use std::unique_ptr with a minimal impact on
out-of-tree code.
Patch by Ahmed Charles with some minor cleanups (and bool casts) by me.

The docs now build cleanly. Yay!
The following warnings were fixed:

This generalizes the code to eliminate extra truncs/exts around i1 bit
operations to also do the same on PPC64 for i32 bit operations. This eliminates
a fairly prevalent code wart:
int foo(int a) {
return a == 5 ? 7 : 8;
}
On PPC64, because of the extension implied by the ABI, this would generate:
cmplwi 0, 3, 5
li 12, 8
li 4, 7
isel 3, 4, 12, 2
rldicl 3, 3, 0, 32
blr
where the 'rldicl 3, 3, 0, 32', the extension, is completely unnecessary. At
least for the single-BB case (which is all that the DAG combine mechanism can
handle), this unnecessary extension is no longer generated.

to the build being C++11.
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.
