d18dd0a7b0 Handle '.' correctly in hex float literal parsing.
There were a couple of different loops that were not handling
'.' correctly in APFloat::convertFromHexadecimalString; these mistakes
could lead to assertion failures and incorrect rounding for overlong
hex float literals.

Fixes PR16643.

5982da1002 [APFloat] Rename isIEEENormal => isNormal and remove old isNormal method.
The old isNormal is already functionally replaced by the method isFiniteNonZero
in r184350 and all references to said method were replaced in LLVM/clang in
r184356/134366.

c82a0b3e6d [APFloat] Added isFiniteNonZero predicate.
This is the first patch in a series of patches to rename isNormal =>
isFiniteNonZero and isIEEENormal => isNormal. In order to prevent careless
errors on my part the overall plan is:

1. Add the isFiniteNonZero predicate with tests. I can do this in a method
independent of isNormal. (This step is this patch).
2. Convert all references to isNormal with isFiniteNonZero. My plan is to
comment out isNormal locally and continually convert isNormal references =>
isFiniteNonZero until llvm/clang compiles.
3. Remove old isNormal and rename isIEEENormal to isNormal.
4. Look through all of said references from patch 2 and see if we can simplify
them by using the new isNormal.

b152f55b6e IEEE-754R 5.7.2 General Operations is* operations (except for isCanonical).
Specifically the following work was done:

1. If the operation was not implemented, I implemented it.

2. If the operation was already implemented, I just moved its location
in the APFloat header into the IEEE-754R 5.7.2 section. If the name was
incorrect, I put in a comment giving the true IEEE-754R name.

Also unittests have been added for all of the functions which did not
already have a unittest.

58a7392486 ADT: Correct APInt::getActiveWords for zero values
PR15138 was opened because of a segfault in the Bitcode writer.
The actual issue ended up being a bug in APInt where calls to
APInt::getActiveWords returns a bogus value when the APInt value
is 0.  This patch fixes the problem by ensuring that getActiveWords
returns 1 for 0 valued APInts.

ff647f94ab Introduce a new data structure, the SparseMultiSet, and changes to the MI scheduler to use it.
A SparseMultiSet adds multiset behavior to SparseSet, while retaining SparseSet's desirable properties. Essentially, SparseMultiSet provides multiset behavior by storing its dense data in doubly linked lists that are inlined into the dense vector. This allows it to provide good data locality as well as vector-like constant-time clear() and fast constant time find(), insert(), and erase(). It also allows SparseMultiSet to have a builtin recycler rather than keeping SparseSet's behavior of always swapping upon removal, which allows it to preserve more iterators. It's often a better alternative to a SparseSet of a growable container or vector-of-vector.

499d789d2b Add an iplist::clearAndLeakNodesUnsafely() function.
The iplist::clear() function can be quite expensive because it traverses
the entire list, calling deleteNode() and removeNodeFromList() on each
element. If node destruction and deallocation can be handled some other
way, clearAndLeakNodesUnsafely() can be used to jettison all nodes
without bringing them into cache.

The function name is meant to be ominous.

223ce5e130 Add an assertion for a likely ilist::splice() contract violation.
The single-element ilist::splice() function supports a noop move:

  List.splice(I, List, I);

The corresponding std::list function doesn't allow that, so add a unit
test to document that behavior.

This also means that

  List.splice(I, List, F);

is somewhat surprisingly not equivalent to

  List.splice(I, List, F, next(F));

This patch adds an assertion to catch the illegal case I == F above.
Alternatively, we could make I == F a legal noop, but that would make
ilist differ even more from std::list.

5286042938 Switch LLVM_USE_RVALUE_REFERENCES to LLVM_HAS_RVALUE_REFERENCES.
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.

c504e37126 Implement arithmetic on APFloat with PPCDoubleDouble semantics by
treating it as if it were an IEEE floating-point type with 106-bit
mantissa.

This makes compile-time arithmetic on "long double" for PowerPC
in clang (in particular parsing of floating point constants)
work, and fixes all "long double" related failures in the test
suite.
