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.

* wrap code blocks in \code ... \endcode;
* refer to parameter names in paragraphs correctly (\arg is not what most
people want -- it starts a new paragraph);
* use \param instead of \arg to document parameters in order to be consistent
with the rest of the codebase.

Most of the code guarded with ANDROIDEABI are not
ARM-specific, and having no relation with arm-eabi.
Thus, it will be more natural to call this
environment "Android" instead of "ANDROIDEABI".
Note: We are not using ANDROID because several projects
are using "-DANDROID" as the conditional compilation
flag.

Changes the hash result for strings containing characters
with values >= 128, such as UTF8 strings (not normal ASCII).
Changed mostly so we match other implementations.

Adds the vendor 'fsl' (used by Freescale SDK) to Triple. This will allow
clang support for Freescale cross-compile configurations.

TinyPtrVector. With these, it is sufficiently functional for my more
normal / pedestrian uses.
I've not included some r-value reference stuff here because the value
type for a TinyPtrVector is, necessarily, just a pointer.
I've added tests that cover the basic behavior of these routines, but
they aren't as comprehensive as I'd like. In particular, they don't
really test the iterator semantics as thoroughly as they should. Maybe
some brave soul will feel enterprising and flesh them out. ;]
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161104 91177308-0d34-0410-b5e6-96231b3b80d8
for this class. These tests exercise most of the basic properties, but
the API for TinyPtrVector is very strange currently. My plan is to start
fleshing out the API to match that of SmallVector, but I wanted a test
for what is there first.
Sadly, it doesn't look reasonable to just re-use the SmallVector tests,
as this container can only ever store pointers, and much of the
SmallVector testing is to get construction and destruction right.
Just to get this basic test working, I had to add value_type to the
interface.
While here I found a subtle bug in the combination of 'erase', 'begin',
and 'end'. Both 'begin' and 'end' wanted to use a null pointer to
indicate the "end" iterator of an empty vector, regardless of whether
there is actually a vector allocated or the pointer union is null.
Everything else was fine with this except for erase. If you erase the
last element of a vector after it has held more than one element, we
return the end iterator of the underlying SmallVector which need not be
a null pointer. Instead, simply use the pointer, and poniter + size()
begin/end definitions in the tiny case, and delegate to the inner vector
whenever it is present.
