8cf8d64d19 Allow inlining of functions with returns_twice calls, if they have the 
attribute themselve.

e16533eded Use the fancy new VariadicFunction template instead of a plain variadic function. 
Some compilers were complaining about passing StringRef to it.

f9c9d1b4d0 capitalize project name, reference bugzilla 
And fix the double-[]. It was including the [] as part of
the project name somehow, resulting in PACKAGE_TARNAME "-llvm-"
and a strange docdir default:

./configure --help | grep docdir
  --docdir=DIR           documentation root [DATAROOTDIR/doc/-llvm-]

b870a13cd8 Revert 146728 as it's causing failures on some of the external bots as well as 
internal nightly testers.  Original commit message:

By popular demand, link up types by name if they are isomorphic and one is an
autorenamed version of the other.   This makes the IR easier to read, because
we don't end up with random renamed versions of the types after LTO'ing a large
app.

c8e6351626 As Doug pointed out (and I really should know), it is perfectly easy to 
make VariadicFunction actually be trivial. Do so, and also make it look
more like your standard trivial functor by making it a struct with no
access specifiers. The unit test is updated to initialize its functors
properly.

0ec73f6e98 SimplifyCFG now predicts some conditional branches to true or false depending on previous branch on same comparison operands. 
For example, 

if (a == b) {
    if (a > b) // this is false

9c8c9a8f62 The powers that be have decided that LLVM IR should now support 16-bit 
"half precision" floating-point with a first-class type.

This patch adds basic IR support (but not codegen support).

38b0b94ef2 When recursing for the original size of a type, stop if we are at a 
pointer or a reference type - we actually just want the size of the
pointer then for that.

d0c1eb9dd2 Don't adjust for alignment padding in OffsetIsInRange. 
This adjustment is already included in the block offsets computed by
BasicBlockInfo, and adjusting again here can cause the pass to loop.

When CreateNewWater splits a basic block, OffsetIsInRange would reject
the new CPE on the next pass because of the too conservative alignment
adjustment. This caused the block to be split again, and so on.

3d0382e29d Note ARM constant island alignment in the release notes. 
The command line option should be removed, but not until the feature has
gotten a lot of testing. The ARMConstantIslandPass tends to have subtle
bugs that only show up after a while.

can, or whose bug it is. Grr.

1cf4d2d1ae Add a generic collection of class templates to ADT for building 
variadic-like functions in C++98. See the comments in the header file
for a more detailed description of how these work. We plan to use these
extensively in the AST matching library. This code and idea were
originally authored by Zhanyong Wan. I've condensed it using macros
to reduce repeatition and adjusted it to fit better with LLVM's ADT.

Thanks to both David Blaikie and Doug Gregor for the review!

can reconsider later if we ever get pluggable targets.
