This is an alternative to the ImmutableMapRef interface where a factory
should still be canonicalizing by default, but in certain cases an
improvement can be made by delaying the canonicalization.

textually as NativeClient. Also added a link to the native client project for
readers unfamiliar with it.
A Clang patch will follow shortly.

AKA: Recompile *ALL* the source code!
This one went much better. No manual edits here. I spot-checked for
silliness and grep-checked for really broken edits and everything seemed
good. It all still compiles. Yell if you see something that looks goofy.

Rationale:
1) This was the name in the comment block. ;]
2) It matches Clang's __has_feature naming convention.
3) It matches other compiler-feature-test conventions.
Sorry for the noise. =]
I've also switch the comment block to use a \brief tag and not duplicate
the name.

references from whether it supports an R-value reference *this. No
version of GCC today supports the latter, which breaks GCC C++11
compiles of LLVM and Clang now.
Also add doxygen comments clarifying what's going on here, and update
the usage in Optional. I'll update the usages in Clang next.

This expands to '&', and is intended to be used when an /optional/ rvalue
override is available.
Before:
void foo() const { ... }
After:
void foo() const LLVM_LVALUE_FUNCTION { ... }
void foo() && { ... }
This is used to allow moving the contents of an Optional.

Similarly to several recent fixes throughout the code replace std::map use with the MapVector.
Add find() method to the MapVector.

APInt::shl generated llvm.trap to guard against shifts greater than bit-width.
This was already checked with an assert, and there was a special case for
shifts equal to bit-width. Modify this check to catch shifts greater than or
equal to bit-width, so llvm.trap isn't generated.

While LLVM itself is still C++03, there's no reason why tools built on
top of it can't use C++11 features.

This allows llvm::Optional to be used with movable-but-not-copyable types.

most of the behavior we want, but wrap the predicate in one which erases
elements from the set if they pass the predicate. Oh what I wouldn't
give for a lambda here.
Let me know if the predicate wrapping is too much magic. ;]

preserves the values of the relocated entries, unlikely remove_if. This
allows walking them and erasing them.
Also flesh out the predicate we are using for this to support the
various constraints actually imposed on a UnaryPredicate -- without this
we can't compose it with std::not1.
Thanks to Sean Silva for the review here and noticing the issue with
std::remove_if.

scheduled for processing on the worklist eventually gets deleted while
we are processing another alloca, fixing the original test case in
PR13990.
To facilitate this, add a remove_if helper to the SetVector abstraction.
It's not easy to use the standard abstractions for this because of the
specifics of SetVectors types and implementation.
Finally, a nice small test case is included. Thanks to Benjamin for the
fantastic reduced test case here! All I had to do was delete some empty
basic blocks!

This adds 'elf' as a recognized target triple environment value and overrides the default generated object format on Windows platforms if that value is present. This patch also enables MCJIT tests on Windows using the new environment value.

This silences literally dozens of analyzer warnings on LLVM (since DenseMap
is such a commonly-used class).

provide insertion order iteration, instead of the old option of
DenseMap order iteration over keys and insertion order iteration over
values.
This is implemented by keeping two copies of each key.
